Similarly, we could have constructed OM on the 0-degree line first then placed point O on the 30 degree measure to draw OM. 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.
(corner) of the angle and that the base line of the protractor is along. For example, to draw ∠OMP having a measure of 30°: When measuring angles, make sure that the centre of the protractor is over the vertex. Protractors can also be used to draw an angle having a specific measure. It is marked with degrees from 0 to 180 degrees. Then, read the degree measure on the outside set of numbers where side TS intersects the edge of the protractor. A protractor is a semi-circular tool used to draw and measure angles.

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.Create panel > (Helpers) > Standard > Object Type rollout >. Whichever side you line up with the zero-degree line determines which set of numbers to use. Protractor measures the angle between a point and any two objects in your scene. 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 (°).

Make sure you are reading off the correct set of markings. By lining up these scales, you can measure angles accurately and get the right answer. The device has a number scale that goes from zero to 180 degrees, with one side of the angle lining up with 0 on its inner scale and a cosine scale on its outer scale. Note: there are two scale markings corresponding to left-to-right ( black) and right-to-left ( blue) angle measurement. A protractor is a tool used in mathematics to calculate angles. Angles within 2 degrees will be marked as correct.

Look where the diagonal line crosses the protractor to determine the number of degrees in the acute angle.
Line up the horizontal line on the baseline of your protractor, placing the center of your protractor over the vertex.

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.
