The diagram shows the base line, PQ, of triangle PQR.
Point R can move so that the area of the triangle PQR is always the same. Sketch the locus of the point R.
The diagram shows a line, PQ that is 7.6cm (I measured it0
Does this mean I should use perpendicular bisector?

The area will remain the same if the base of the triangle and the perpendicular height are unchanged. This is achieved if the top point of the triangle moves along a line parallel to the base.
