Question

can anyone solve this please​

Answer 1

Step-by-step explanation:

4 th vertex is equal to (7,4)

Answer 2

Answer:

(4,3). IN

Step-by-step explanation:

let D(x,y) be the fourth vertex. slope = m , since it is a || gram then ,

mAB = mCD & mAD = mBC

slope of BC = (y2 - y1)/(x2 - x1)

= (5-3)/(8-2) = 2/6 = 1/3

slope of AD (mAD) = mBC

(y - 2)/(x - 1) = 1/3

y = 3 & x = 4 satisfies here.

so the fourth vertex is D(4,3)
