Answer :

The given angle is negative

Adding or subtracting 360° from a particular angle does’nt changes its position.

Therefore, Angle can also be written as=-40° + 360° = 320° • 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 320° 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. Rate this question :
