What is the vertex of an angle?

Back

The vertex of an angle is the point where the two rays meet.

What are the different types of angles based on their measurements?

Back

Angles can be classified as acute (less than 90 degrees), right (exactly 90 degrees), obtuse (greater than 90 degrees but less than 180 degrees), straight (exactly 180 degrees), reflex (greater than 180 degrees but less than 360 degrees), and full rotation (360 degrees).

How do you measure an angle?

Back

An angle is measured in degrees using a protractor, which aligns with one ray and allows the other ray to indicate the measurement.
