To be able to establish the measure of an angle by using its complementary (example of the javelin and of the inclined road).

To teach how to place a protractor in order to properly measure an angle.

Read the graduation that follows the second side of the angleĬlick and drag the protractor and its blue handles to make some measurements.Align the 0° graduation of the protractor with one of the side of the angle.

Position the origin of the protractor on the tip of the angle to measure.

The most common units of measures for angles are the degree (°) and the radian (rad).

To facilitate its usage, the protractor often possesses two graduations going in both directions.

Another form of protractors available would be the full disc graduated from 0 to 360°. The first example below with the default values used in the calculator above calculates the miter saw angle to 26.4 degrees for length a 33.5, b 40 and c 39.1. The protractor is graduated from 0 to 180 degrees (°). The most popular version is the half disc split into 180 equal parts that each correspond to one degree. The tool used to measure angles is the protractor. The intersection of the lines is the tip of the angle. Similarly, we could have constructed OM on the 0-degree line first then placed point O on the 30 degree measure to draw OM.This animation illustrates how to use a protractor to measure an angle.Ĭlick and drag the protractor and its blue handles to make some measurements.Ī plan angle defines the space on the plan delimited by two crossing lines. 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°: These electrical and electronics engineering calculators are to help electronics/circuit designers to solve complex equations and calculations quickly. I have it, and it works good, but it would definitely get a higher review if this feature was for free, as this seems like it could definitely be more useful for people who don’t want to spend money on an app when they don’t. However, this isn’t really useful unless you purchase the camera feature for 0.99. Protractors can also be used to draw an angle having a specific measure. I recently downloaded this app because I didn’t have a spare protractor on me. 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.
