Which of the following steps is INCORRECT while constructing an angle of 60°?
Step-1 : Draw a line EF and mark a point O on it.
Step-2 : Place the pointer of the compass at O and draw an arc of convenient radius which cuts the line EF at point P.
Step-3 : With the pointer at A (as centre) now draw an arc that passes through O.
Step-4 : Let the two arcs intersect at Q. Join OQ. We get ∠QOP whose measure is 60°.
A Only Step-1
B Both Step-2 and Step-3
C Only Step-3
D Both Step-3 and Step-4
I think the answer is D
