A right angle is a type of angle that measures exactly 90 degrees

A right angle is a type of angle that measures exactly 90 degrees. It is formed when two lines or line segments meet or intersect to form a square corner. In a right angle, the two sides or rays are perpendicular to each other, meaning they are at a 90-degree angle to each other.

A right angle can be represented using a small square or by using the symbol “∟”. The sides of a right angle are called the legs, and the point where they meet is called the vertex or corner. In geometry, right angles are very important and commonly used in various applications. They can be found in the corners of squares, rectangles, and cubes.

Right angles have several properties, including:

1. Perpendicularity: The two sides or rays of a right angle are perpendicular, meaning they intersect at a 90-degree angle.
2. Bisecting: A right angle bisects the straight line, dividing it into two equal parts.
3. Congruency: All right angles are congruent, meaning they have the same angle measure of 90 degrees.

Right angles are widely used in geometry, trigonometry, and other branches of mathematics. They are fundamental in many geometric concepts such as angles, polygons, and coordinate grids. Understanding and recognizing right angles is essential for solving various math problems and real-world applications.
