How many degrees are in a right angle?

• A. 45 degrees
• B. 90 degrees
• C. 180 degrees
• D. 360 degrees

Answer: (B)

A right angle is defined as an angle that measures exactly 90 degrees. This measurement is a fundamental concept in geometry and is crucial for constructing shapes and understanding various mathematical principles. A right angle represents the angle formed when two lines meet at a perpendicular intersection, creating a square corner, which can be visually identified in many everyday objects, such as books, tables, and computer screens. The other angles listed, such as 45 degrees, 180 degrees, and 360 degrees, represent different types of angles: 45 degrees is an acute angle, 180 degrees is a straight angle, and 360 degrees represents a full rotation. Understanding the concept of a right angle and its measurement of 90 degrees is essential for problem-solving in many mathematical contexts.
