A triangle has sides measuring 15, 15, and 15 . What are the angle measures of the triangle?
2 answers:
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.
The angle measures are 60, 60, 60
