1. What forms the sides of both regular and irregular polygons? line segments
3. What do you call the common point where two sides of a polygon meet to form an angle? vertex
4. What word would you use when you talk about more than one vertex? vertices
5. What do you know aboutthe number of sides, angles, and vertices of a polygon? They are the same.
7 sides 4 angles hexa- 3 angles 7 vertices quad- 8 vertices 6 vertices octa- 6 sides 5 angles tri- 8 angles 3 sides penta- 4 sides 5 vertices
triangle 3 sides 3 angles
quadrilateral 4 sides 4 angles
pentagon 5 sides 5 angles
hexagon 6 sides 6 angles
octagon 8 sides 8 angles
