"In triangle ABC, angle A is a right angle, angle B measures 60 degrees."
So ABC is a 30-60-90 triangle (because
are the angle measures).
If A is the right angle, then BC (opposite o angle A) is the hypotenuse.
AB and AC are legs of the right triangle.
Consider an equilateral triangle> It has three
angles and is split by each altitude into two congruent 30-60-90 triangles.9 (Call one of those angles, angle B).
In each of those right triangles, the short leg is half as long as the hypotenuse (BC), so for the smallest angle
