if a bracket 1, 2 bracket of B 4 bracket 3 bracket of C6 A6 othe
r word three vertex of a parallelogram ABCD find the coordinates of fourth vertex
d

Answer 1

Answer:

Step-by-step explanation:

Let D(a,b) be the 4th vertex.

Midpoint of AC = (1+6/2,2+6/2) = (7/2,4)        

Midpoint of BD = (a+4/2,b+3/2)

a+4/2 = 7/2 , b+3/2 = 4

a + 4 = 7, b + 3 = 8

a = 3, b = 5

Hope this helps!
