A pentagon can be broken up into three triangles.
since all triangles measure 180 degrees, we can say that the sum of the interior angles of a pentagon is
180 * 3
540 degrees
hope this helps
Pentagon = 5 sided polygon.
[tex] \boxed {\text {Sum of all interior angles = (n - 2) x 180}} [/tex]
Given that n = 5,
Sum of all interior angles = (5 - 2) x 180 = 540°
Answer: 540°
