Q1 A of 13 Page 96

Let’s see the isosceles triangles given below and without measuring let’s write which two sides are equal in length in each triangle.


It is given that ∆ABC is isosceles and

∠A=70°


∠B=40°


And ∠C=70°


∴ ∠A=∠C


We know angles opposite to the equal sides are equal.


So, BA=BC
