Answer:

90 degrees

Step by Step Explanation:
  1. A rectangle is a parallelogram in which all the four angles are equal.
  2. Let us understand this through the following illustration:
  3. In the above figure, ABCD is a parallelogram which is a rectangle. We find that all the four sides as well as the angles are equal in measure such that ∠A = ∠B = ∠C = ∠D.
  4. We know that the sum of all the four angles of a parallelogram is 360°. Since, all the four angles of a rectangle are equal, this means the measure of each angle is  
    360
    4
      = 90°.
  5. Hence, the measure of each interior angle of a rectangle is 90°.
