Find The Sum Of The Measures Of Exterior Angles Of A Regular Triangle. This may be one the most well known mathematical rules-The sum of all 3 interior angles in a triangle is 180circ. Hence the sum of the 3 exterior angles of a triangle is also 360 Sum of 2 of these angles are given as 264.
The exterior angles taken one at each vertex always sum up to 360. The sum of the exterior angles of any polygon is 360 degrees. If a polygon is convex then the sum of the measures of the exterior angles one at each vertex is 360.
We have three sides so our n is 3.
Therefore all its exterior angles measure the same as well that is 120 degrees. If a polygon is convex then the sum of the measures of the exterior angles one at each vertex is 360. Every triangle has six exterior angles two at each vertex are equal in measure. We have three sides so our n is 3.
