=__//Symmetry in polygons//__= - the dogs face is symmetrical

-learn polygons -use the reflectioinal symmetry and rotational symmetry. -learn regular polygon, center of a regular polygon, center angle of a regular polygon, and axis of symmetry.
 * Objectives**

__polygon-__ a figure formed by three or more segments and at each endpoint each segment intersects exactly at two other segments and no two segments are colliner. __sides of the polygon__- the segments of a polygon. __vertices of the polygon__- the common endpoints of a polygon. __equiangular polygon__-all angles are congruent. __equilateral polygon-__ all sides are congruent. __regular polygon-__ all angles are congruent and all sides are congruent. __reflectional symmetry-__ reflection across the line is exactly the same. __axis of semmetry-__ the line that is reflectied across. __triangles classified by number of congruent sides-__ three congruent sides: equilateral no congruent sides: scalene at least two congruent sides: isosceles __Rotational symmetry__- has to have at least one rotation, that is not 0 degrees or multiples of 360 degrees that coincides with the original image.
