Measure them with a protractor
No because an exterior angle and an interior angle of a polygon add up to 180 degrees but exterior angles around a polygon add up to 360 degrees
A rectangle (or square).
If the polygon has n sides, each exterior angle is 360/n degrees.The interior angle is 180 less exterior angle.
...eight interior and exterior angles. ANGLES
1980 interior angles and 360 exterior angles
The exterior and interior angles of each vertex of a polygon add up to 180 degrees.
A Regular Polygon
octagon interior=135 exterior=45
Any irregular polygon does not have equal sides and equal interior angles
The sum of each pair of interior and exterior angles of a polygon is always 180 degrees.
The easiest way to solve this is to use the exterior angles of the polygon. The sum of an exterior angle and interior angle is 180o. Also the sum of all the exterior angles of a polygon is 360o. As the polygon is regular, all the interior angles are the same and all the exterior angles are the same. So, for an interior angle of 172o the exterior angle is 180-172 = 8o. The sum of all the exterior angles is 360o so how many 8o make up 360o? 360/8=45. Thus the polygon with interior angles of 172o has 45 sides.
If you multiply 360 by the number of angles in the polygon and then subtract the sum of all the interior angles you will end up with the sum of all the exterior angles of the polygon.
No because an exterior angle and an interior angle of a polygon add up to 180 degrees but exterior angles around a polygon add up to 360 degrees
An equilateral triangle.
In a polygon there are no such angles.
