Proof Of Angle Sum Property Of Quadrilateral Class 9 Ma 1. the angles of a quadrilateral are in the ratio 3 : 5 : 9 : 13. find all the angles of the quadrilateral. solution: let the common ratio between the angles be x. we know that the sum of the interior angles of the quadrilateral = 360°. now, 3x 5x 9x 13x = 360°. ⇒ 30x = 360°. Updated from new ncert books 2023 24. get solutions of all ncert questions, exercises and theorems of chapter 8 class 9 quadrilateral free at teachoo. answers to all questions have been solved in an easy way, with video of each and every question. in this chapter, we will learn . what is a quadrilateral. angle sum property of a quadrilateral.
Quadrilateral Sum Theorem Ex 8.1 class 9 maths question 1. the angles of quadrilateral are in the ratio 3 : 5 : 9 : 13. find all the angles of the quadrilateral. solution: let the angles of the quadrilateral be 3x, 5x, 9x and 13x. ∴ 3x 5x 9x 13x = 360°. [angle sum property of a quadrilateral] ⇒ 30x = 360°. ⇒ x = 360∘ 30 = 12°. 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°.
