## Explain How To Use A Protractor To Measure An Angle

A right angle is 90˚, a straight line angle is 180˚ and a full turn is 360˚.We use a protractor (also called an angle measurer) to measure degrees. We explain what degrees are and how children are taught to use protractors to measure angles, as well as reviewing the different knowledge children acquire about angles throughout KS1 and KS2.

- Now, we will use a protractor to measure the reflex angle PQR. To measure the reflex angle PQR, extend the arm PQ to A to form angle PQA which is a straight angle. Then measure the size of the angle AQR and add 180º. Key Terms. point, angle,
- If you have a protractor that only measures 0 to 90 degrees, explain how to use this protractor to find the measure of an obtuse angle.
- Explain how to use a protractor to measure an angle. Put the steps in the correct order Use the greater number for an obtuse angle and the lesser number for an acute angle.
- You can use a protractor to measure an angle by identifying the vertex, or center point, of the angle, placing the origin/center-point of the protractor over the vertex, lining up the bottom edge with one of the angle edges, and locating the measurement of the angle.
