Quick video on Steps to follow constructing an angle.
Step 1
Use the baseline of the protractor to draw one ray of the angle. Mark
the vertex.
Step 2.
Place the protractor on the ray so that the center is over the vertex of
the angle to be drawn.
Step 3
On the scale of the protractor, find the number of degrees for the angle
to be drawn. Make a mark (point) next to the number of degrees.
Step 4
Use the baseline of the protractor to connect the point and the vertex
of the angle.
Step 5
Draw a ray from the vertex to the point.
Use a protractor to draw these angles.
