# More on Angles

While you are working independently this morning, you may like to use this site to help you with remembering about angles.

Here are some handy tips for working with a protractor:

Angles are measured using a protractor. You can guess the rough size of an angle by looking to see if it’s acute or obtuse, but you’ll need a protractor for a precise measurement.

Here’s how to use a protractor to measure an angle:

• Line up the protractor so the ‘cross hair’ is exactly on the angle.
• Line up one of the lines with the 0 line on the protractor.
• See which numbers the angle comes between. If it is between 30 and 40, the angle must be thirty something degrees.

Count the small degrees up from 30. In this example, the angle is 35°.

When you’re done, you may like to give these two activities a go as well. The first game requires you to make the angles in order to make targets.
