Right Triangle

A right triangle is a three-sided shape with one angle exactly 90 degrees, called the right angle. It has two sides that meet at this right angle, called the legs, and a third side called the hypotenuse, which is opposite the right angle and usually the longest side. Right triangles are fundamental in geometry, used to measure distances and angles, and are the basis for the Pythagorean theorem, which relates the lengths of the sides. They appear in various real-world applications such as construction, navigation, and design.
