The angle measures are 60, 60, 60

Esmeralda · Answer 2

Since all sides are of the same length, all angles must be of the same magnitude as well.

The sum of the angles of any triangle must equal 180° so we can say:

3α=180 upon dividing both sides by 3 we see:

α=60°

So all of the angles are 60° which is true for all equilateral triangles.
