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

OpenStudy (anonymous):

BD=CE= Square Root of 50. BC= CD =DE = EB = Square root of 50

OpenStudy (anonymous):

so what's the question?

OpenStudy (anonymous):

It is asking me to verify that BCDE is a rhombus with those specific vertices.

OpenStudy (anonymous):

I need help choosing the correct statement that shows it is true.

OpenStudy (anonymous):

Well, you found the length of each side is sqrt(50), so it is an equilateral parallelogram, thus, it is a rhombus.

OpenStudy (anonymous):

So would that mean it would be D.?

OpenStudy (anonymous):

Does D say that they are all equal to sqrt(50)? I just can't read that entirely.

OpenStudy (anonymous):

D. says BC = CD = DE = EB = sqrt(50)

OpenStudy (anonymous):

That is correct.

OpenStudy (anonymous):

Ok thanks :D. May i ask another one or should i create a new question?

OpenStudy (anonymous):

sure
