Question

show that all angle of equilateral triangle is 60°​

Answer 1

Explanation:

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°.

hope it helps you

thanks

Answer 2

Answer:

➡️Given= Sum of all sides of the triangle is 180.

➡️To proof = all angle of equilateral triangle is 60°

➡️Proof=

Since all the sides in equilateral triangle are equal ,Angles are also equal

Let it be x

The Angle sum property of triangle is 180

x+x+x=180

3x=180

x= 3/ 180

=60 °
