Find the equation

Answer :

Given: the vertices of triangle ABC are A (4, 3), B (0, 0) and C (2, 3).


To find:


The equation of bisector of angle A.


Explanation:


Let us find the lengths of sides AB and AC.


AB = 5


AC = = 2


We know that the internal bisector AD of angle BAC divides BC in the ratio AB: AC, i.e. 5: 2


D


Thus, the equation of AD is


Formula used:




x – 3y +5 = 0


Hence, the equation of line is x – 3y +5 = 0
