The triangle with angles measuring 40, 50, and 90 degrees is a right triangle. In a right triangle, one of the angles is always 90 degrees, making it a right-angled triangle. The other two angles are acute angles, measuring less than 90 degrees each. The sum of the interior angles of any triangle is always 180 degrees.
