(ii) altitude through vertex A
(iii) perpendicular bisector of side BC
​

Answer 1

Answer:

if A(1,4) B(2,-3) and C(-1-2) are the vertices of triangle ABC find the equation of

(i) median through vertex A

$d = ( \frac{2 - 1}{2} . \: \frac{ - 3 - 1}{2} ) \\ d(0.5 \: \: - 2.5)$

(ii) altitude through vertex A

(iii) perpendicular bisector of side BC
