Question

Q12. If ABC is an equilateral triangle, then each angle equals to:



120 degree

80 degree

60 degree

180 degree

​

Answer 1

Answer:

60°

Step-by-step explanation:

In an equilateral triangle, all the angles are equal.

Let the angles be x, x and x.

We know that,

Sum of all angles in a triangle = 180°

On substituting our assumed values, we have,

x+x+x = 180°

3x = 180°

x = 180°/3

x = 60°.

Therefore, each angle of an equilateral triangle is 60°.

Hope it helps you.

Good Luck.
