Front

What is the degree measure of a right angle?

What is the degree measure of an acute angle?

Back

An acute angle measures less than 90 degrees.

Front

What is the degree measure of an obtuse angle?

Back

An obtuse angle measures more than 90 degrees but less than 180 degrees.

Front

What is a straight angle?

Back

A straight angle measures exactly 180 degrees.

Front

How do you read a protractor?

To read a protractor, align the baseline of the protractor with one ray of the angle and read the measurement where the other ray crosses the numbered scale.

Front

What is the degree measure of a reflex angle?

Back

A reflex angle measures more than 180 degrees but less than 360 degrees.

Front

If an angle measures 37 degrees, is it acute, obtuse, or right?

Back

It is an acute angle because it measures less than 90 degrees.

Front

If an angle measures 150 degrees, is it acute, obtuse, or right?

Back

It is an obtuse angle because it measures more than 90 degrees but less than 180 degrees.
