Question

what is the total measure of internal angles of a pentagon ​

Answer 1

If it is a Regular Polygon (all sides are equal, all angles are equal)

Shape Sides Each Angle

Triangle 3 60°

Quadrilateral 4 90°

Pentagon 5 108°

If it is a Regular Polygon (all sides are equal, all angles are equal

From vertex A we can draw two diagonals which separates the pentagon into three triangles. We multiply 3 times 180 degrees to find the sum of all the interior angles of a pentagon, which is 540 degrees.

540°

540°The sum of the internal angles in a simple pentagon is 540°.
