The sum of the five interior angles of ANY pentagon is 540 degrees.If the pentagon is regular, then each angle is 108 degrees.
The sum of the exterior angles of any polygon is 360 degrees.
A pentagon is a plane area which is enclosed by five straight lines. It is, therefore, a polygon. The sum of the five interior angles of a pentagon sum to 540 degrees and so, each interior angle of a regular pentagon measures 108 degrees. A pentagon has five diagonals. It can have none of five axes of symmetry.
Sum_of_interior_angles = 180o x (number_of_sides - 2) So for a pentagon with 5 sides: sum = 180o x (5 - 2) = 540o
The 5 interior angles of any pentagon add up to 540 degrees
