I drew a line through Q, T and P, and proved that the two triangles (BQT and APT) are congruent (angles in the same segment and vert. opposite angles). And as they lie on the line, the points had to be collinear. Hope its right :angel:

The triangles aren't congruent. Unless you mean similar, which assumes the result.

reckon you'd get a mark for doing it by assuming it was a straight line for stating alternate angles on the one that is given as a line?
