Question

PQR is a right-angled triangle with the right angle at Q and k being the length of the perpendicular from Q on PR. If l, m and n are the lengths of sides PQ, QR, and PR respectively, then which of the following holds true?

Answer 1

Answer:

In triangles PQS and PQR P is common to both.and PSQ = PQR Triangles PQS and PQR are equiangular PS/PQ = QS/QR or, PS = PQ·QS/QR ...(i)Again, triangles ...
