Arrange the given steps in correct order of constructing an angle of 90° using ruler and compass.
Step 1 : Place the pointer of the compasses at O and draw an arc of convenient radius which cuts the line at A.
Step 2 : Without disturbing radius on compasses, draw an arc with A as centre which cuts the first arc at B.
Step 3 : With B and C as centres and with any convenient radius, draw two arcs to intersect each other at L.
Step 4 : Again without disturbing the radius on the compasses and with B as centre, draw an arc which cuts the first arc at C.
Step 5 : Draw any line PQ and take a point O on it.
Step 6 : Join OL.
∠LOA is the required angle whose measure is 90°.
