Question

Which angle has the largest measure among an acute angle, an obtuse angle, a right angle or a reflex angle?

Accepted Answer

In geometry, an angle is formed when two rays are joined at their end points. These rays are called the arms of the angle.

An angle which measures less than $90 °$ is called an acute angle. Example: $30 °, 68 °, 75 °, . . . . .$

An angle which measures greater than $90 °$ is called an obtuse angle. Example: $95 °, 100, 135 °, . . . . . . .$

An angle which measures $90 °$ is called a right angle.

An angle which measures more than $180 °$ and less than $360 °$ is called a reflex angle. Example: $190 °, 268 °, 300 °, . . . . .$

Since a reflex angle measures more than $180 °$ but less than $360 °$ , we can say that a reflex angle has the largest measure when compared to an acute angle, an obtuse angle and a right angle.

Therefore, the largest measure among an acute angle, an obtuse angle, a right angle or a reflex angle is a reflex angle.

Which angle has the largest measure among an acute angle, an obtuse angle, a right angle or a reflex angle?
