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 xy

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

step-by-step explanation:

so then what are you asking?

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
