Question

Classify each polygon by its number of sides.

Answer 1

Shape three is a decagon

shape two is a dodecagon

shape one is a "hexagon" has 6 sides

Answer 2

Answer:  

A 2-dimension closed figures with a number of sides is called Polygon.

If it has 7 sides it is called Heptagon,

If it has 12 sides it is called Dodecagon,

If it has 6 sides it is called Hexagon,

If it has 10 sides it is called Decagon,

If it has 8 sides it is called octagon,

If it has 5 sides it is called Pentagon,

Since, First figure has 6 sides therefore, it is a hexagon,

While, Second figure has 12 sides therefore, why it is a Dodecagon,

And, Third figure has 10 sides therefore, it is a Decagon.
