### What is Meant by the Right Angle?

In mathematics, a triangle is a two-dimensional figure with three sides. The triangle can be classified into different types based on the sides and angles. Based on the sides, the triangle can be classified as a scalene triangle, isosceles triangle, equilateral triangle. Based on the angles, the triangle can be classified as an acute triangle, obtuse triangle, and right triangle. The right triangle is a triangle, where one of the angles is at right angle (i.e., 90 degrees). The relation between the angles and the sides of the right triangle is well explained in trigonometry.
