Question

Karen says every equilateral triangle is acute. Is this true?
Explain

Answer 1

An equilateral triangle has the three sides equal. So the three angles are equal.

Since sum of angles in a triangle = 180°

For each = 180° / 3 = 60°

And 60° is an acute angle.

So every equilateral triangle is acute in that it contains only acute angles.

So it is True.
