What are the names to polygons from 3 to 100 sides?



3: Triangle

4: Quadrilateral

5: Pentagon

6: Hexagon

7: Heptagon

8: Octagon

9: Nonagon

10: Decagon

There are names for some polygons with a higher number of sides, but these are rarely used. Typically we use the phrase "n-gon." Thus, a 69-sided polygon would be referred to as a 69-gon.
