Which of the following steps is INCORRECT while constructing a rhombus ABCD, given that AC = 8 cm and BD = 6 cm?
Step 1 :Draw AC = 8 cm.
Step 2 :Draw PQ, the perpendicular of AC. PQ intersects AC at point O.
Step 3 :With O as centre and radius equal to 3 cm, drawn an arc cutting OP at D.
Step 4 :With O as centre and radius equal to 3 cm, draw another arc cutting OQ at B.
Step 5 :Join AB, BC, CD and DA.
A Step 2 only
B Step 3 only
C Step 4 only
D Both Step 2 and Step 5
how is step 2 wrong ?
