How many degrees are there in a right angle?

  1. 90 degrees

  2. 180 degrees

  3. 360 degrees

  4. 45 degrees

The correct answer is: 90 degrees

A right angle is defined as an angle that measures exactly 90 degrees. This is a standard measurement used in geometry to describe the angle formed when two lines intersect perpendicularly. In contrast, an angle measuring 180 degrees corresponds to a straight angle, where the two lines are collinear. A full rotation around a point is represented by an angle of 360 degrees, and a 45-degree angle is smaller than a right angle, representing a quarter of the right angle measurement. Therefore, understanding that a right angle is specifically designated as 90 degrees is essential for solving problems related to angles in mathematics.
