I WONDER - What Are The Different Types Of Angles Called?

The video tutorial explains different types of angles in geometry. It starts with right angles, which measure 90 degrees and are represented by a small square inside the angle. It then describes acute angles as those measuring less than 90 degrees, and obtuse angles as those measuring more than 90 degrees but less than 180 degrees. Reflex angles are defined as angles measuring more than 180 degrees, while a straight angle measures exactly 180 degrees.

What is the measure of a right angle?

• 90 degrees
