WebThe sum of the interior angles in a triangle is supplementary. In other words, the sum of the measure of the interior angles of a triangle equals 180°. So, the formula of the triangle sum theorem can be written as, for a triangle ABC, we have ∠A + ∠B + ∠C = 180°. WebJan 2, 2024 · I = 180° – E. where, I is the value of the interior angle E is the corresponding exterior angle for that interior angle. Using Sum of Interior Angles. We know that all the interior angles of a regular polygon are equal. So, the measure of each interior angle of a regular polygon is equal to the sum of the interior angles of the polygon divided by the …
