162o.
Method 1: Sum of interior angles of n-sided polygon = (2n - 4) right angles.
In this case n = 20 so total of interior angles is 36 x 90o. Assuming polygon is regular then each interior angle is (36 x 90) divided by 20 = 3240/20 = 162.
Method 2: Exterior angles of regular n-sided polygon = 360/n which in this case = 360/20 =18. Straight line is 180o so interior angle = (180 - exterior angle) = 180 - 18 = 162.
If measured on the inside of the polygon, the it is an interior angle.
The interior angles of a 15 sided polygon add up to 2340 degrees
(15-2)*180 =2340
A polygon is a closed plane figure bounded by straight sides. Since it is a closed surface, it has an interior (inside) and an exterior (outside). The interior angle of a polygon is the angle formed by two adjacent sides such that the angle is facing the interior of the polygon.
The interior angle of a polygon and its adjacent exterior angle can never be complementary.

No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more.

interior angle of an n-sided polygon = (180(n-2)/n)°interior angle of a 24-sided polygon = (180x22/24)° = 165°
Any polygon can have an interior angle of 144 degrees. The measurement of an interior angle of a decagon is 144 degrees.
160
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
Each interior angle in 12-sided polygon is 150 degrees.
The angle inside a polygon. Simple!
