Expressiveness of lines

Vertical line: They express an asundent or descendent movement, depending on how they are used
Horizontal line: They produced visual feeling of stability and colaess or triangulity
Skew lines expressiveness: They produced unsteadiness and movements feelings

Hatching

It is a way of shading of givings tones to the areas of object or surfaces with parallels lines
Cross hatching: It´sa way of shanding areas of a drawing or surface with paralalles lines in several directions
Dashed/or dotted/lines:They are lines which are not continous, formed by little traces or dots
Blurred: They are very soft or vanished so they are hard to see and opposite to intense and deep
Siplem lines: Those that are formed by only one line
Composite lines: They are lines composite by fragments of several straight and curved lines

Line

It can be defined as a dot in moviment it has a position a direction in the space and one of its principal function consists on marking the shapes outlines
Line zig zag or broken lines: They are formed by several fragments of straigh lines with different directions
Wavy line: They are formed by several fragments of curved lines
Curly lines: They hold more curves than many lines and shaw loops
Scribble: Chaotic on meanringless lines that are traed radouly or to fill in some are with a particular texture

Basic Elements Of Visual Representation

Dot: t is the smallest and most simple elements in art expression. It may have different qualities such as size. Shape and colour
The dot tee dimensional capacity: When the size, shapes and colour changed, the dots can create visual sensations of spacial deepness and volumeç
The dot expresive capacity: The point has a unlimited capacity to represent images an to express ideas and emotions
Optical mix: When colours are mired with the help of distance. Paint isn´t mixed on the palette or on the painting

COMPLEMENTARY COLOUR

There are pairs of colours with are locoted one in front of ich other on the colour wheel
Warm range: It is a scale of colours that has either more yellow, more magenta, or both in its mixture
Cold/cool range: It is a scale of colours that has more cyan or blue in its mixture than any other colours
Grey scale: It is a set of colours which only has any colours between black and white, it contains a scale of greys

COLOR

It is a element of visual language. It is a light impression that arrives to the eyes which send information to the brain
Epigmen: It is the sustance that made the material for paint and the origin can be mineral, animal
Hue: Also called toned or tint, it is the name of the colour defined by its wavelenght
Saturation: Degree of purity of a color. If a color is very satured it means that it is very pure and doesn´t have many colours in its mix
Value: Sometimes called brightness or luminosity It is the amount of black or white that a colour has in its mix

TEXTURE

Texture: It is yhe visual tactile quality of the surfaces due to the material
Tactile texture: Are those that can be percived through the sense of touch
Visual textures: Those which can only be percived through the sense of sight
Natural texture: Those that can be found in nature
Artificial texture: Are those created by the human beging manually or mecanically
Rubbing tecjnique: It consists on frictoning or rubbing a crayon or colored pencil on a thin paper which is over a surface with a tactile texture so the texture gets copied on the paper
Scratchboarding: It is usually done with waxed colors and it consists on giving two coasts of color to the media being the second one darker, so when scrathing over the first layer the second one shows up

SHAPE

Shape: It is athe external appearance of an object or element in an image
Natural shapes: They are teh ones related to nature. They haven´t been created by any human
Organic shapes: They are shapes that have irregular profile or silhoute as well as their inner surface
Artificial shapes: Shapes which have been created by humans or machanical
Geometric shapes: Shapes whose parts follow a mathematic order
Flat shapes: They are two dimensions such a paper sheet

SYMMETRY

It is a quality of som e shapes which some of their parts are reflections of others

AXIS SYMMETRY
It is a shapes quality which is formed by two halves facing each otehr with an axis or fold line in between as if both sides were mirror images of each other.
Symmetry axis: It is a line to divide a shape into two symmetric halves symmetry halves symmetry points are on a perpendicular line to it
Central symmetry: It is the reflection of a object through a point called the symmetryc pair of points are collinear

QUADRILATERALS

They are polygons with two sides and four vertices.
Parallelograms: They are cuadrilaterals with two pairs of parallels opposite equal sides and two pairs of opposite equal angles. Their diagonals bisect each other

IMPORTANT DEFINITIONS AND CLASSIFICATION ABOUT TRIANGLES

Equilateral triangle: It is a triangle which sides and vertices are the same
Isosceles triangle: It is a triangle which has two equal sides and angles 
Scalene triangle:It is a triangle which three different sides and angles

Right triangle: It is a triangle which has one right angle 
Obtuse: Obtuse triangles have one angle which is more than 90o
Acute: All their vertices are acute

THE POLYGONS

Star polygon: It a particular polygon case with a star shape, created out of linking together non consecutive vertices of a regular polygon.

Incribed polygons: They are polygons place inside circles so all vertices of the polygon are placed on the circle.

Circunscribed: They are polygons sorrounding a circle, beging its sides tangent to the circle inside.

Equangular: All their corners angles or vertices are equal.

Equilateral: All edges or sides are of teh same length

Regular: All their vertices, angles and sides are equal

Irregular: Show different angles and length for their angles

HALLOWEEN

To me ,  halloween is a very fun holiday . You can go trick-or trearing and they give the children sweets and you can dress up as a skeleton , zombie , ghost ...

TYPES OF ANGLES

Complementary angles : They are couples of angles which sum is 90º
Suplementary angles : They are couple of angles which sum is 180º
Adyacent angles : They are angles that share onr side and the vertex 

IMPORTANT DEFINITIONS ABOUT CIRCLES

Circle : Set of points at the same distance to a point called center
Circumference : It is the full length of a circle . The complete distance around a circle
Center : It is the point equidistand to any of the points on a circle
Radius : it is the length of a line segment from the center to its perimeter 
Diameter : A line segment that passes through the center and conects two points of a circle . Its lengh is double than the radius
Chord : A line segment which conects two points of the circle not trough the center
Arc : Segment of a circle 
Tangent : Element which touch a circle in one point
Outer : Whwn an element doesn´t touch a circle in one point 
Inner : When an element is fitted inside teh circumference , or another element , being tangent or not
Concentric circles  They are circles with diferent radius but place in the plane sharing the center

IMPORTANT DEFINITIONS ABOUT ANGLES AND LINES

Paralles : THEY ARE LINES WHICH NEVER INTERSEC THEMESELVES SO ALL THEIR
 POINTS ARE EQUIDISTANCE
Perpendicular :  They are lines wich meet forming four riht angles
Oblique / skew : They are lines which are not parallels neither perpendicular
Angle : It is a figure formed by two rays sharing a common endpoint

GEOMETRY DRAWING AND SUPPLIES CONCEPTS AND DEFINITIONS

 FREEHAND: DRAW BY HAND WHIT OUT INSTRUMENTS.

BASIC GEOMETRY CONCEPS AND DEFINITIONS

       
GEOMETRY : It is an area that studies all the elements and operations in a line

POINT : In geometry a point can be defined at places or localitation when two lines interseet . A point hasn`t got dimensions , no height and no width

GREEK : Geo is earth and metry is measurement

LINE : The line is a dimensional object formed infinite points . It hasn`t end and continues on forever in a plane

RAY : It lines that begins in a point and there is not end

MIND POINT : Is the point that is on the midle of a segment

LINE SEGMENT : It is a line with two ends points

 LENGTH : Measurement of something from end to end
