Perimeter of a Rectangle. Note: All the properties of a parallelogram are applicable to rhombus (the ones that consider here are parallel sides, congruence of opposite angles, and supplementary consecutive angles). Solution : Since diagonals of a rectangle bisect each other, Since the sum of the interior angles of a polygon is 36 0 ∘ 360^\circ 3 6 0 ∘, it follows that each of the interior angles is a right angle. So, a rectangle has four right angles. The Perimeter is the distance around the edges. Show that each angle of a rectangle is a right angle. ∴ ∠ C = 90° and ∠ D = 90°. Now, Find out its Length. Since, all the four angles of a rectangle are equal, this means the measure of each angle is 360 4 = 90°. follow. A rectangle with four sides of equal length is a square.
