If it is a regular 8 sided octagon then each exterior angle is 45 degrees and each interior angle is 135 degrees.
Each exterior angle = 630/6 = 60 degrees. So each interior angle = 180 - 60 = 120 degrees.
60 degrees in each angle
Each exterior angle is 30 degrees and each interior angle is 150 degrees
If each exterior angle is 30 degrees the polygon has 360/30 = 12 sides.
A parallelogram, in general, has no right angles.
The interior angles of a parallelogram must total 360o and each opposite pair is also equal; these pairs can be any angle except 90o.
If it is a regular 8 sided octagon then each exterior angle is 45 degrees and each interior angle is 135 degrees.
Each angle of a rectangle measures 90 degrees.
Each angle for a regular nonagon is 140 degrees each.
135 degrees
Each exterior angle is 360/8 = 45 degrees. So each interior angle is 180 - 45 = 135 degrees.
Each exterior angle = 630/6 = 60 degrees. So each interior angle = 180 - 60 = 120 degrees.
Each interior angle of a regular 6 sided hexagon is 120 degrees.
All 4 sided shapes each equal to 360 degrees in angles
60 degrees in each angle
A right angle - whether or not in a rectangle - is 90 degrees.
