Arrange the given steps in correct order of constructing an angle of 30° using ruler and compass. Steps of construction:
(1) Draw a ray AB.
(2) With A as centre and a convenient radius, draw an arc to intersect at X.
(3) Taking Y as a centre and with the same radius draw another arc that cuts the previous arc at C.
(4) With X as a centre, draw an arc with the same radius to intersect the previous arc at Y.
(5) Taking X as a centre and a radius greater than half of XY, draw an arc.
(6) Join A and C to get ray AC. ∠CAB is the required angle.
