              3.  Start counting from zero near B moving in anticlockwise direction, (see inner scale). Mark a
                 point C at 70°.
















              4.  Join AC with the help of a ruler.


















                  Thus, ∠BAC = 70° is the required angle.

            Example 10: Draw an angle of measure 114°.
            Solution: Steps of Construction:


                        1.  Draw a ray PQ. It will be the base of the angle.               P                        Q
                        2.  Place the centre of the protractor at a point P such that its zero edge lies along ray PQ.















                        3.  Start counting from zero near Q. Mark point R at 4th smaller marking after 110°
                            moving in anticlockwise direction along inner scale.
