This document provides a formula for calculating the sum of interior angles of a polygon shape. The formula is (n-2)x180, where n is the number of sides. For a square with 4 sides, the formula would be (4-2)x180=360 degrees, which is the total interior angle measurement of a square.

By; T.J. and Gareth (n-2)x180 Formula for finding the sum of interior angles

Example First you take the number of sides from the shape and minus 2. There are 4 sides on a square so n=4. (n-2)

Y our Answer Then you multiply by 180 and that’s your answer! There are 360 degrees in the square. (4-2) X 180

the END Thanks for watching GOOD BYE!
