Which of these statements is true? a. the interior angles of both a regular and irregular pentagon have a sum of 540o. b. the interior angles of both a regular and irregular pentagon have a sum of 1,080o. c. only a regular pentagon’s interior angles have a sum of 540o. d. only an irregular pentagon’s interior angles have a sum of 540o.

 Option A is the correct answer.

Step-by-step explanation:

 The sum of interior angles of a polygon is given by (n-2) x 180°, where n is the number of sides.

 The sum of interior angles will not affect irregularity of polygon, it is same for regular and irregular polygon.

 For a pentagon n =5.

 Sum of interior angles = (5-2) x 180 = 3 x 180 = 540°

  Option A is the correct answer.
