It is a regular 20 sided polygon
The interior angles of a 17 sided polygon add up to 2700 degrees
If it's a regular polygon then each interior angle measures 120 degrees.
The interior angles add up to 2340 degrees
The 13 interior angles of a 13 sided polygon add up to 1,980 degrees
A heptagon is a seven-sided polygon. It has seven interior angles. If it is a Regular polygon, each interior angle measures approximately 128.57 degrees, to a total of 900 degrees.
The interior angles of a 17 sided polygon add up to 2700 degrees
If it's a regular polygon then each interior angle measures 120 degrees.
There are 5 interior angles and each one measures 108 degrees (180-72). Since the sum of exterior angles of any polygon is 360⁰, then that polygon would have 5 angles (360/72). So the sum of interior angle measures is 540⁰.
If each angle measures 90 degrees the polygon is a square and so its angles sum to 360 degrees.
