Answer 2

construction

Step-by-step explanation:

assuming that the given angles to be drawn are

(1) 60°

steps :

1. Draw a ray OA.
2. With O as centre and any suitable radius draw an arc above OA cutting it at a point B.
3. With B as centre and the same radius as before, draw another arc to cut the previous arc at C.
4. Join OC and produce it to D
5. Then ∠AOD = 60°

(ii)90°

steps :

1. Take any ray OA.
2. With O as centre and any convenient radius, draw an arc cutting OA at B.
3. With B as centre and the same radius, draw an cutting the first arc at C.  With C as centre and the same radius, cut off an arc cutting again the first arc at D.
4. With C and D as centre and radius of more than half of CD, draw two arcs cutting each other at E, join OE.

(iii) 75°

steps :

1. Take a ray OA.
2. With O as centre and any convenient radius, draw an arc cutting OA at C.
3.  With C as centre and the same radius, draw an cutting the first arc at M.
4.  With M as centre and the same radius, cut off an arc cutting again the first arc at L.
5.  With L and M as centre and radius of more than half of LM, draw two arcs cutting each other at B, join OB which is making 90°.
6.  Now with N and M as centres again draw two arcs cutting each other at P.
7.  Join OP.
