Angle Sum Property Of A Quadrilateral Ch 8 Quadrilaterals Cla Some of the most important formulas and concepts covered in these ncert solutions for class 9 maths chapter 8 based on the angle sum property, parallelograms, and mid point theorem are given below: the sum of the angles of a quadrilateral is 360 degrees. a quadrilateral with equal and parallel pairs of opposite sides is called a parallelogram. 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. Important notes on 9th maths chapter 8. 1. sum of the all angles of a quadrilateral is 360. 2. a quadrilateral in which one pair of opposite sides are parallel, is called trapezium. 3. a quadrilateral in which both pairs of opposite sides are parallel, is called parallelogram. 4. 1. the angles of quadrilateral are in the ratio 3 : 5 : 9 : 13. find all the angles of the quadrilateral. answer let x be the common ratio between the angles. sum of the interior angles of the quadrilateral = 360° now, 3x 5x 9x 13x = 360° ⇒ 30x = 360° ⇒ x = 12° angles of the quadrilateral are: 3x = 3×12° = 36° 5x = 5×12° = 60°.
