,Which of these statements is true?

-The interior angles of both a regular and irregular pentagon have a sum of 540 degrees

-The interior angles of both a regular and irregular pentagon have a sum of 1,080 degrees

-Only a regular pentagon’s interior angles have a sum of 540 degrees

OR

-Only an Irregular pentagon’s interior angles have a sum of 540

Answer 1

First of all let's take a triangle, no matter how it looks like, interior angle sum will always be 180, that also apply to every other polygons.

Now, let's find the interior angles' sum of a pentagon

a pentagon is composed of 3 triangle, so the interior angle sum would be 180*3 = 540.
