Answer:

Then each of them is equal to 60 °

Answer:

If all three angles of a triangle are equal, then what is each of them equal to?

As you know, a triangle has 3 angles and the sum of all the angles in a triangle equals to 180 degrees. So if we consider a triangle whose angles are equal i.e., an equiangular or equilateral triangle, then each angle of the triangle is 60 degrees.

See,

Let the vertices of the triangle be A, B, C

Angle A = Angle B = Angle C = x degrees

x+x+x=180 degrees

3x =180 degrees

x=180/3

x= 60 degrees
