Question

Verify that quadrilateral BCDE is a rhombus with vertices B(-5, 1), C(0, 6), D(5, 1) and E (0, -4) by showing that all four sides are equal.

Answer 1

A. BD = CE = square root of 50
B. BD = CE = 50
C. BC = CD = DE = EB = 50
D. BC = CD = DE = EB = square root of 50

Answer 2

Answer 3

Use the distance formula to find the length of each side.
\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Answer 4

for a rhombus all four side have to be equal, so it's has to be c or d

Answer 5

Ok. I think C am I correct, or do you not know the answer?

Answer 6

I know, but you actually have to put two of the points into the formula. You won't get 50 when you do that

Answer 7

Oh ok I get it now it is D

Answer 8

yes
