Find The Measure Of One Interior Angle Calculator. This calculator is designed to give the angles of any regular polygon. In order to find the value of the interior angle of a regular polygon the equation is n 2180 n where n is the number of sides of the regular polygon.
The triangle angle calculator finds the missing angles in triangle. Arcsin 14 in sin 30 9 in. Some common polygon total angle measures are as follows.
Additionally if we have a regular polygon ie all sides and angles are equal then we can find the measure of each interior angle by dividing the sum of the interior angles by the number of sides.
T riangle using Heron. The measure of each interior angle of a regular n-gon is. Square 4 2180. Alternatively multiply this length by tan θ to get the length of the side opposite to the angle.
