WebThere are six basic types of quadrilaterals: 1. Rectangle Opposite sides are parallel and equal. All angles are 90º. The diagonals bisect each other. 2. Square Opposite sides are parallel and all sides are equal. All angles are … WebSolution Since, diagonals of a quadrilateral bisect each other, so it is a parallelogram. Therefore, the sum of interior angles between two parallel lines is 180° i.e., ∠A+∠B = 180° => ∠B = 180° – ∠A = 180°- 35° [∴ ∠A = 35°, given] ⇒ ∠B = 145° Suggest Corrections 1 Similar questions Q.
