Angle Sum Property Of A Quadrilateral Sum Of Angles Class 9 Youtube This is section 8.2 of class 9 curriculum. you will learn to prove angle sum property of quadrilateral which states that sum of all four internal angles of a. 1. find the fourth angle of a quadrilateral whose angles are 90°, 45° and 60°. solution: by the angle sum property we know; sum of all the interior angles of a quadrilateral = 360°. let the unknown angle be x. so, 90° 45° 60° x = 360°. 195° x = 360°. x = 360° – 195°. Angle sum property in quadrilaterals. we have seen that in any triangle, the sum of the three angles is 180 0. in any quadrilateral, the sum of the four angles is 360 0. the following figure shows an example: this fact will hold true even if one of the angles of the quadrilaterals is reflex, as shown below: the justification of the angle sum. Hence, the sum of all the four angles of a quadrilateral is 360°. solved examples of angle sum property of a quadrilateral: 1. the angle of a quadrilateral are (3x 2)°, (x – 3), (2x 1)°, 2(2x 5)° respectively. find the value of x and the measure of each angle. solution:.
