(number of sides - 2)*180 = sum of interior angles
by using a protractor
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
Using a protractor is the simplest way of solving the measurements of angles.

A protractor is normally used to construct angles.
To accurately measure angles using a protractor, place the center of the protractor on the vertex of the angle. Align one side of the angle with the zero line on the protractor. Read the measurement where the other side of the angle intersects the protractor scale.
