Question

Why are all equilateral triangles acute?

Answer 1

All the angles are `60^o`.

Explanation:

In a equilateral triangle, all the angles are equal. All the angles in a triangle sum up to `180^o`. We can determine the angles by dividing 180 by 3 (the three angles) to get 60. Therefore we can determine that each angle is `60^o`. All acute angles are below `90^o`.
