(i) Yes. (ii) Yes. (iii) No; an isosceles trapezium also has equal diagonals. Extra condition: the quadrilateral must be a parallelogram or its diagonals must also bisect each other. Ganita Manjari Part 2 chapter 12 question answer Quadrilaterals Solutions – Ganita ...
Since AB ∥ CD and AD ∥ BC, alternate angles are equal. Because AC bisects ∠A, adjacent angles match, proving AC bisects ∠C. In △ABC, equal base angles imply AB = BC, making all sides equal. Cbse released Class 9 Ganita ...
(i) True: Adjacent angles sum to 180°, making every angle 90°. (ii) False: Every rhombus has perpendicular diagonals; it needs a right angle to be a square. (iii) True: Equal diagonals in a parallelogram ensure four right angles. Cbse Class 9 ...
It will not work directly as described because pairs are generated out of order. The algorithm relies on an ascending list to pick the rightmost element as the GCD, requiring sorting first. Class 9 Ganita Manjari Part 2 chapter 11 question ...
We only need to examine numbers from 1 up to ⌊√n⌋. Because any divisor d larger than √n pairs with a quotient n/d smaller than √n, testing up to √n finds them all. Class 9 Chapter 11 The World of Algorithms ...
