## The Degree Symbol: °

We use a little circle ° following the number to mean degrees.

For example 90° means 90 degrees

## Measuring Degrees

We often measure degrees using a protractor:

The normal protractor measures 0° to 180°

## Measuring

 Protractors usually have two sets of numbers goingin opposite directions.Be careful which one you use!When in doubt think "should this angle be bigger orsmaller than 90° ?"

Type of Angle Description Acute Angle an angle that is less than 90° Right Angle an angle that is 90° exactly Obtuse Angle an angle that is greater than 90° but less than 180° Straight Angle an angle that is 180° exactly

## Parts of an Angle

The corner point of an angle is called the vertex

And the two straight sides are called arms

The angle is the amount of turn between each arm.

You can be a "pro" at using a protractor!
