**What is an Angle Measure? **

In geometry, an angle measure can be defined as the measure of the angle formed by the two rays or arms at a common vertex.

Angles are measured in degrees ( °), using a protractor.

## Let's sing!

*An acute angle is a little so small,*

*Right angle in the corner of a wall,*

*Obtuse angle at 2:50 in day-time,*

*Straight angle in a straw in soda-lime!*

*So many angles all around, even in a mime!*

## Let's do it!

Model and show how to use a protractor correctly. Ask your child to then use the protractor to measure and identify angles, basis their measurement.
