-Define the term polyon -Define and se the reflectional symmetry and rotational symmetry -Define the terms regular polygon, center of a regular plygon, central angle of a regular polygon, central angle of a regular polygon, and axis of symmetry.
 * __LAURA'S SYMETRY IN POLYGONS__**
 * //Objectives://**

__Polygon__: a plane figure formed from three or more segments so that each segment intersects exactly two other segments, one at each endpoint, and no two segments wigh a common endpoint are collinear. __Sides of the Polygon:__ segments of a polygon. __Vertices of the Polygon:__ Common endpoints of a Polygon. __Axis of Symmetry:__ a line that coincieds exactly with the preimage. __Equiangular polygon__: a polygon where all angles are congruent. __Equilateral polygon:__ a polygon where all sides are congruent. __Regular Polygon__: a polygon that is both equiangular and equilateral __Center of a Regular Polygon__: the point of a polygon that is equidistant from all vertices of the polygon __Central Angle__: a regular polygon that has an angle whose vertex is the center of the polygon and sides pass through two consecutive vertices.

//**Theroms:**// __Reflectional Symetry:__ A figure has reflectional symmetry if and only if its reflected image across the line coincedes exacly with the preimage. __Rotational Symmetry:__ A figure has rotational symmetry if ad only if it has at least one rotation image, not conting the rotation of images of 0° or the multiles of 360° that coincides with the original image. http://www.mathsisfun.com/geometry/polygons.html http://www.haelmedia.com/OnlineActivities_txh/mc_txh4_001.html
