If the middle points of the sides `B C ,C A ,` and `A B` of triangle `A B C` are `(1,3),(5,7),` and `(-5,7),` respectively, then find the equation of the side `A Bdot`

Text Solution

Verified by Experts

The correct Answer is:
x-y+12=0

Slope of DE `=(7-3)/(5-1) = 1`
Slope of AB =1
Hence, the equation of AB is
y-7=x+5
or x-y+12=0
