Consider a triangle PQR with coordinates...

Consider a triangle PQR with coordinates of its vertices as P(-8,5), Q(-15, -19), and R (1, -7). The bisector of the interior angle of P has the equation which can be written in the form ax+2y+c=0.
The distance between the orthocenter and the circumcenter of triangle PQR is

A

`25//2`

B

`29//2`

C

`37//2`

D

`51//2`

Text Solution

Verified by Experts

The correct Answer is:
A

Since the triangle is right-angled, the circumcenter is the midpoint of PQ and the orthocenter is R(1, -7). Hence,

`RM = |sqrt(((23)/(2) + 1)^(2))| = 12(1)/(2)`
