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
