How do you find the sum of the interior angles of a pentagon?

To answer this question, you’ll use your knowledge that the sum of the interior angles of any pentagon is always 540 degrees. All you have to do is to subtract your four known angles from the total of 540 degrees. Doing this, you find your answer to be this: 540 – 135 – 78 – 119 – 117 = 91 degrees.

What is the sum of all the angles of a pentagon?

So if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Hexagon has 6, so we take A heptagon has 7 sides, so we take the hexagon’s sum of interior angles and add 180 to it getting us, degrees.
