If all of the interior angles of the polygon add up to 180 degrees, then the polygon is a triangle.
The exterior angles of any polygon add up to 360.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 6660 degrees.
measure of exterior angle of triangle is equal to sum of interior angles. for eg. In triangle ABC, angle C is exterior angle angle A and angle B are interior angles so, C=A+B
The sum of the exterior angles of a regular polygon equal 360° . If one such angle measures 36° then the polygon has 360/36 = 10 sides.
Square or rectangle
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
4 such as a square
When all sides are equal and all interior and exterior angles are equal.
That's true of any polygon with four sides.
Interior angles are equal and sides are equal in length and exterior angles add up to 360 degrees
The total of the interior angles equal 5040, and each angle measures 168 degrees The total of the exterior angles equal 360, and each angle measures 12 degrees
The sum of the exterior angles of a polygon is equal to 360 degrees.
