The end of diagonals of a rhombus are (-5,2) and (1,6).if the coordinates of the 3rd vertex are (-6,10).what are the coordinates of the 4th vertex? a. (2,-2) ,0) c. (4,8) d. (-9,8)

Hi there!

Diagonals of a rhombus bisect each other.

This means th't both the diagonals must have the same mid-point.

Hence, the midpt. of the diagonal through vertices.

by Mid-point formula :-

∴ [ , ] = [ , ]

→ For x :--

=> - 6 + x = - 4

=> x = 6 - 4

=> x = 2

→ For y :--

=> 10 + y = 8

=> y = 8 - 10

=> y = -2

Therefore, Th' fourth vertex is (x, y) = (2, -2)

Hence,
Option [ A. ] : (2, -2) is Correct

~ Hope it helps!

Geometric pattern of 2 i’m guessing. not really sure about what you’re asking but i hope this !
