Polygons Day 2

A polygon is a ​ (a)   figure with ​ (b)   or more sides.

• closed
• three
• open
• four
• five
• six
• eight

What is the definition of vertices?

• Vertices are where lines meet to form an angle.

• Vertices are the amount of turn between two straight lines.

• Vertices are a closed figure with 4 sides and 4 angles.

• Vertices are a straight line joining vertices.

A quadrilateral is a ​ (a)   figure with ​ (b)   sides and four ​ (c)  

• closed
• four
• angles.
• open
• three
• fifth
• sides
• vertices

Congruent means the ​ (a)   ​ (b)   and the same ​ (c)  

• same
• size
• shape.
• different
