Given: the coordinates of rhombus wxyz are w(0, 4b), x(2a, 0), y(0, −4b), and z(−2a, 0).
prove: the segments joining the midpoints of a rhombus form a rectangle.
as part of the proof, find the midpoint of wz

-a,2b

Step-by-step explanation:

here is your answer

Option C

Step-by-step explanation:

In this question coordinates of rhombus WXYZ are given as W(0, 4b), X(2a, 0), Y(0, −4b), and Z(−2a, 0).

Now we have to find the coordinates of midpoint of WZ as part of the proof.

Since mid point of two points (x, y) and (x', y') is represented by

For midpoint of WZ,

= (-a, 2b)

Option C will be the answer.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
