Question

In triangle PQR , PQ and PR are altitude of triangle​

Answer 1

Answer:

Hint: Here, it is given that PQ and PR are two altitudes of triangle PQR. We see that in two altitude vertex P is common. Therefore, the angle between the two sides PQ and PR of the triangle is $ {90^0} $ . Hence, either of them is treated as altitude and other as base or vice versa.
