Question: 1 / 400

How many degrees are there in a right angle?

45 degrees

90 degrees

A right angle is defined as an angle that measures exactly 90 degrees. This measurement is crucial in geometry and various fields including construction, engineering, and design, where right angles are fundamental in creating perpendicular lines and shapes. In everyday life, 90 degrees represents a quarter of a full rotation, accounting for its prevalence in various practical applications.

In contrast, 45 degrees represents an acute angle, which is less than a right angle. A 180-degree angle indicates a straight line, while 360 degrees refers to a complete rotation or a full circle. Understanding these distinctions underscores why 90 degrees is recognized as the measure of a right angle.
