Each of the four interior angles of a square (i.e. a regular quadrilateral) measures 90 degrees
An interior angle of a regular octagon is 45 degrees. The exterior angles measure 315 degrees.
The interior angles add up to 360 degrees.
A pentagon (five sided regular polygon) has interior angles of 108°.
This is a tautological question that does not have a proper answer. A regular polygon is one which has all its sides of equal length and all its interior angles of equal measure.
Interior angles of a regular 18 gon (octdecagon) are 160o.
Only when it is a regular polygon that all interior angles are of equal measure
If you mean a regular pentagon then each of its 5 interior angles measures 108 degrees
900
9
1350
It is: 135 degrees
108 degrees
540 degrees
Only if the polygon is "regular".
No.
this depends on what type of polygon it is.. if it is a regular triangle, then all interior angles measure up to 180 degrees. So, a triangles interior angles would measure 60 degrees each.
