Question

If AB=BC=AC , then prove that angle A=angle B= angle C​

Answer 1

Step-by-step explanation:

Let, the angle of side AB = x

(if the side of the triangle is equal then it's the angle is also the same)

According to the question, AB=BC=AC

therefore, x= angle of BC= angle of AC

Now,

x+x+x =180°

3x= 180°

x=180°/3

x= 60°

therefore, angle A= 60° = angle B= angle C
