A right triangle is defined as having one angle measuring exactly 90 degrees, also known as a right angle. Therefore, the correct answer is 90 degrees. Option A, 95 degrees, is incorrect because it is greater than 90 degrees. Option C, 180 degrees, is incorrect because that would make the triangle a straight line, not a triangle. Option D, 360 degrees, is incorrect because that is equivalent to two full rotations, not just one angle in a triangle.
