Any polygon with at least 7 sides CAN have 5 right angles.
what is the equation to figure the angles of a polygon?
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.
Exterior angles 360 degrees Interior angles 540 degrees
The sum of the exterior angles of a polygon is 360o.
