    Something wrong with this rhombus coordination

    hello Guys i think i have an error with my Coordinations here for a project. ( I believe i wrote it down) I found all the length are congruent but when I am trying to find all sides one of them is 10/4 instead of 4/10 IDK what to do.

    ( Coordinates here)

    Sorry for that

    exactly what are you asking us?

    i checked one of the distances and got 10.77, not 10/4 or 4/10.

    eg, CA:
    CA = \sqrt{(2-6)^2 + (3-13)^2)}
    CA = \sqrt{(-4)^2 + (-10)^2)}
    CA = \sqrt{116}
    CA = 10.77....

    Same thing (DO NOT show as 10/4 or 4/10):
    4 and 10 : sqrt(16 + 100) = sqrt(116)
    10 and 4 : sqrt(100 + 16) = sqrt(116)

    Hello, vaironxxrd!

    C(2,3),\;A(6,13),\;S(16,17),\;H(12,7)

    With answers like \frac{10}{4} and \frac{4}{10},
    . . you are obviously determining the slopes of the sides.

    But why?

    What was the original question?

    Hi vaironxxrd,
    Were you asked to prove that the four point formed a rhombus? If so you did well.All four sides have. the right slopes proving that opposite sides are parallel.The slope diagrams are congruent so the lines are all equal.You were a little confused at the end but you do not have to show the length rad 116 for the sides
