How many degrees are in a right angle?

A right angle is defined as an angle that measures exactly 90 degrees. It is one of the fundamental angles in geometry and is typically represented by a square corner, such as in the edges of a piece of paper or the intersection of two perpendicular lines.

The concept of right angles is crucial in various fields, including construction, engineering, and design, as it ensures accuracy and consistency in creating right-angled shapes. A right angle serves as a standard benchmark against which other angles are measured.

The measurement of 90 degrees is universally accepted in both mathematical principles and real-world applications, making it a cornerstone in geometric studies.
