What is a polygon with 17 sides?

What is a polygon with 17 sides?

In geometry, a heptadecagon, septadecagon or 17-gon is a seventeen-sided polygon.

What is the name of a 18 sided polygon?

An 18-sided polygon, sometimes also called an octakaidecagon.

What is the sum of the interior angles of a polygon that has 17 sides?

Explanation: A heptadecagon ( 17 sided polygon) can be dissected into 15 triangles whose internal angles sum to the sum of the internal angles of the heptadecagon. The internal angles of a (plane) triangle sum to π radians or 180∘ . Note that 17 is a Fermat prime since 17=222−1 is of the form 22n−1 .
