Description : NCERT Solutions for class 9 Maths Chapter 7 Triangles Exercise 7.2 -Maths 9th
Last Answer : 1. In an isosceles triangle ABC, with AB = AC, the bisectors of B and ∠C intersect each other at O. Join A to O. Show that: (i) OB = OC (ii) AO bisects ∠ A (i) In ΔABC, we have AB = AC ... 180° or x =(180o/3) = 60° ∴ ∠A= ∠B = ∠C = 60° Thus, the angles of an equilateral triangle are 60° each.
