Question

Chapter 7
1. Prove that the angles of an equilateral triangle are 60° each​

Answer 1

For an equilateral triangle, we know that all 3 sides of the triangle are equal. Accordingly, all the 3 sides of the equilateral triangle hold equal angles.

Since, we know, that the sum of all angles of any triangle be 180° .

Let each angle be a.

Thus,

Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.

Answer 2

Answer:

Accordingly, all the 3 sides of the equilateral triangle hold equal angles. Since, we know, that the sum of all angles of any triangle be 180° . ... Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.
