A triangle has two angles of 45 degrees; what is the third angle?

Explanation:
The essential rule here is that the angles in a triangle add up to 180 degrees. With two angles of 45 degrees each, they sum to 90 degrees, leaving the third angle as 180 − 90 = 90 degrees. That makes the triangle a right triangle (a 45-45-90 triangle). The other candidate values wouldn’t bring the total to 180—for example, 60 would give 150, 45 would give 135, and 135 would give 225.
