Page 1 27 ME NT AL MA T HS Shapes and Designs Summary Open Figures: The figures whose ends do not meet are called open figures. Example: Closed Figures: The figures whose ends meet are known as closed figures. Example: Polygon: It is a closed figure formed by line segments. For examples Triangle Quadrilateral Pentagon (3 sides) (4 sides) (5 sides) Page 2 27 ME NT AL MA T HS Shapes and Designs Summary Open Figures: The figures whose ends do not meet are called open figures.

Face: The surface of a solid is called its face. Edge: The line where two faces meet is called an edge. Vertex: The point where two or more edges meet is called a vertex. 3-D shape No. of faces No. of Vertices No. of Edges (sides) 1. Cube 6 flat faces 8 12 2.
