The line PQ is altitude of the triangle. This can be obtained by understanding what an altitude is.
Properties of altitude of a triangle:
In the given triangle,
it is clear that angle Q is 90° and therefore PQ is a perpendicular line from the point P.
Since the perpendicular line, which is PQ, is drawn from the vertex, which is P of the triangle to the opposite side, which is SR.
Thus PQ is the altitude of the triangle.
Hence in the given figure, the line PQ is the altitude of the triangle.
