How To Use A Protractor

How To Use A Protractor. First, put the vertex at the center of the protractor. The higher the degree, the more open the angle is.

To measure an angle using a protractor, place the center of your protractor at the vertex of the angle, which is where the two lines come to a point. This worksheet is designed for high school lead students (esl/ell new canadians & refugees who have significant gaps in their education). They can also be used to draw angles.

They Can Also Be Used To Draw Angles.

Change the position of the protractor where the line ob is a straight edge to the protractor. You can use the digital protractor to find an angle measurement that does not yet exist by laying the digital protractor flat on the flat plane and raising it slowly until you have reached the desired angle. The vertex is the point where the two arms meet.

There Are Two Types Of Protractor That Your Child Might Use.

How to use a protractor. For example, to draw ∠omp having a measure of 30°: The following steps can be used to draw angles using a protractor.

Place The Protractor On The Vertex Of The Base Line, And Draw A Dotted Line For 180°.

∠mln is the angle formed by points m, l, and n with a vertex at point l. 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. Flip the paper, keep the protractor on the vertex, and measure from the dotted line to the angle line.

If you get them all correct, they will add up to 180°. Read the degrees where the other side crosses the number scale. Then, measure the size of the opening that the two arms form.

First, Make Sure That You Correctly Identify The Angle In Question.

How to measure an angle with a protractor. The protractor can measure from 0 to 180°, if an angle is greater than 180° you turn the protractor upside down and measure the angle from the baseline, then add 180°. First, put the vertex at the center of the protractor.
