BASIC 2-Dimensional SHAPES OF GEOMETRY

Basic Vocabulary 2-Dimensional  Shapes that have only 2 dimensions; width & height Congruent  Exactly equal in size & shape Polygon  Closed figure where all the sides are mutually congruent Quadrilateral  Polygon with 4 sides Open  Not all the lines that make up the shape connect Closed  All the lines that make up the shape are connected, there are no gaps in the outline of the shape
