Question

Draw an angle of 120 degree and bisect it ( draw 120 degree using pair of compass

Answer 1

Answer: given below

Step-by-step explanation:

1) Draw a horizontal line(a ray, to be precise) and mark it's starting point as O.

2)Now take your compass and adjust any suitable angle in it.

3)With the starting point of the ray (i.e. , O) as the centre, draw a semicircle, touching the ray.

4)Now without changing the angle of compass, keep it on the point where the semicircle touches the ray (say P)

5)Draw an arc which intersects the semicircle at a point (say A)

6) Now keep the compass at A and draw an arc, which intersects the semicircle at a point ( say B)

7)Now draw a ray from O to B and extend it. This is 120°[We are halfway done]

8)Now keep your compass with a definite angle at P and draw an arc inside the angle.

9) Similarly, with B as centre(with the same angle in compass), draw an arc which intersects the previously drawn arc at a point ( say C)

10)Now draw a ray from O to C and extend it. This is the bisector line.

Hope it helps.

Answer 2

Answer :

$\bigstar\; \boxed{\sf Refer\;to\;\;the\;attachment\;for\;the\;figure.}}$

Steps of Construction :

1. Draw an angle of ∠AOB of 120°.

2. Draw an arc from point O.

This arc will cut the ray OA at any point C and ray OB at any point D.

3. Draw two arcs of the same radii from the points C and D as centres.

4. Join the point O to the point M by a ray OM.

The ray OM will cut the angle ∠AOB into equal parts.

5. m∠AOM = m∠BOM =  $\dfrac{120^{\circ}}{2} = 60^{\circ}$
