What is the difference between acute and obtuse angles?

Back

An acute angle measures less than 90 degrees, while an obtuse angle measures more than 90 degrees.

Front

How can angles be named using three points?

Back

Angles can be named using three points, with the vertex point in the middle, such as Angle ABC.

Front
