Answer 2

Answer:

To draw an angle with a protractor, proceed as follows:

Draw a straight line (i.e. an arm of the angle).

Place a dot at one end of the arm.  This dot represents the vertex of the angle.

Place the centre of the protractor at the vertex dot and the baseline of the protractor along the arm of the angle.

Find the required angle on the scale and then mark a small dot at the edge of the protractor.

Join the small dot to the vertex with a ruler to form the second arm of the angle.

Label the angle with capital letters.

Draw a straight line AB.

Place a dot at B.  This dot represents the vertex of the angle.

Place the centre of the protractor at B and the baseline of the protractor along the arm BA.

Find 60º on the scale and mark a small dot at the edge of the protractor.

Join the vertex B to the small dot with a ruler to form the second arm, BC, of the angle.

Mark the angle with a small arc as shown below.
