At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
The sum of a regular polygon's exterior angles is 360. 360 divided by 3 is 120.
It is the regular equilateral triangle whose each exterior angle is 120 degrees
Providing that it's a regular decagon then each exterior angle will measure 36 degrees
Each exterior angle measures 120 degrees
the exterior angle theorem
Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.
