How many degrees are in a right angle?

A right angle is defined as the angle that creates a perfect square corner, which measures exactly 90 degrees. This measurement is foundational in geometry and is used to determine the perpendicularity of two lines. A right angle is significant in various applications, from constructing buildings to creating accurate drawings and ensuring that objects are aligned correctly. The unit of measure for angles is degrees, and 90 degrees represents a quarter of a full rotation (360 degrees). The other angle measures, such as 180 degrees, represent a straight line; 270 degrees represents three-quarters of a full rotation, and 360 degrees returns to the starting point of the circle. Thus, 90 degrees is the precise measurement that characterizes a right angle.
