Question

Draw
an
acute angled ∆PQR Draw its all of
altitude. Name
the point of concurrence as o
​

Answer 1

Answer: So, PL is the altitude on side QR. In the same manner, draw QM⊥PR and RN⊥PQ. Hence, ∆PQR is the required triangle with altitudes PL, QM and RN on sides QR, RP and PQ respectively with O as the point of concurrence of all the three altitudes.
