Question

To construct an angle of 75°using Ruler and Compass only, we have to draw angles ---------------first.
1) 60° and 90°
2) 90° and 120°
3) 45° and 90°
4) 90° and 105°
​

Answer 1

Answer:

1

Step-by-step explanation:

Step of Construction:

(i) Take a ray OA.

(ii) With O as centre and any convenient radius, draw an arc cutting OA at C.

(iii) With C as centre and the same radius, draw an cutting the first arc at M.

(iv) With M as centre and the same radius, cut off an arc cutting again the first arc at L.

(v) 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°.

(vi) Now with N and M as centres again draw two arcs cutting each other at P.

(vii) Join OP.

Answer 2

Answer:

1) 60 and 90

Step-by-step explanation:

angle 75° is formed by cutting of the two arcs drawn from angle 60 and angle 90
