A is (2,3)
B is (6,1)
Lets take the vector approach. Now
vector AB = B-A = (4,-2)
Perpendicular vector with same length as AB passing through C is given by BC
where BC = ( 2,-4)
Thus Vector C = B + BC = (8,-3) or 8-3i
use the same approach to get D. Message me if you need more clarifications. would be glad to help.
