Download the questions as a PDF worksheet Share the link with all your remote students during zoom class and practice measuring the same set of angles, or assign the same set of questions as homework to the whole class. Use the URL displayed at the top to load the same set of angles. Keep practicing with new questionsĬlick the “New Questions” button to generate a new set of questions. Make sure you are reading off the correct set of markings. Note: there are two scale markings corresponding to left-to-right ( black) and right-to-left ( blue) angle measurement. Angles within 2 degrees will be marked as correct. Check your answersĮnter your answers in the respective boxes, then click “Check Answers” button to check your answers. Protractor is highlighted in red when rotating. Rotate the on-screen protractor using (desktop) shift-key + left mouse drag or (tablet) two-finger touch and rotate. Protractor is highlighted in green when moving. Move the on-screen protractor using (desktop) left mouse drag or (tablet) single finger touch and drag. Using the interactive protractor app on screen To use it, align the horizontal line on the protractor to one of the two lines that make up the angle you want to measure, then read off the angle on the appropriate scale on the curve edge of the protractor. Similarly, we could have constructed OM on the 0-degree line first then placed point O on the 30 degree measure to draw OM.More about the Protractor Practice App What is a Protractor?Ī protractor is a tool to help you measure angles, kind of like a ruler, but with degrees markings on a circular edge. We could also construct ∠OMP by placing OM on the 0 degree line on the right side of the protractor as long as vertex M is centered at the midpoint of the protractor.

Lastly, draw segment MP with a straight edge.

Then find 30 on the outside set of degree measures and mark it with point P.

First, draw a line segment OM and put the protractor on the line such that vertex M lies on the midpoint of the protractor and OM lines up with the 0 line on the left side of the protractor.

For example, to draw ∠OMP having a measure of 30°: Protractors can also be used to draw an angle having a specific measure. Then, read the degree measure on the outside set of numbers where side TS intersects the edge of the protractor.

Similarly, you can place TV so the vertex is inside the hole of the protractor and lines up with the 0 line to the left side of the protractor.

Second, make sure that TV is extended enough such that it goes through the edge of the protractor, then read the degree measure on the inner set of numbers where side TV intersects the protractors edge.

First, place side TS so the vertex is inside the hole (the midpoint) of the protractor and TS lines up with the 0 line to the right.Whichever side you line up with the zero-degree line determines which set of numbers to use.

When using a protractor, notice that the outside set of numbers goes from 0 to 180 degrees where the 0 is on the left side of the protractor while the inner set goes from 180 to 0 degrees where 0 is on the right side of the protractor. Most protractors measure angles in degrees (°). Home / geometry / angle / protractor ProtractorĪ protractor is a tool used to measure angles.
