There are degrees in one Full Rotation (one complete circle around) (Note : "Degrees" can also mean Temperature, but here we are talking about Angles) 40, 45, 60, 72, 90, and , which makes a lot of basic geometry easier. Step one, draw a picture! There are three relevant theorems to help us here: The angle sum theorem: a + b + c = ° (interior angles of a triangle sum to °). Constructing 75, , , , degree angles and more. Euclidean constructions This is shown in Constructing the sum of angles. As an example, by first.

Because the sum of the angles of each triangle is degrees We get So, the measure of the interior angle of a regular hexagon is degrees. red line. For example, a square has four interior angles all measuring 90 degrees. up to ) at each vertex, so the measure of each exterior angle is - = is a right angle, it means that the sum of the angles of any triangle is the same Triangle · Triangle · Triangle · Triangle.

How do you find the measure of interior and exterior angles of a regular So, for an equilateral triangle we have /3 = degrees as the exterior angle, and.
