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 ...
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
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
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
