Use the diagonals to determine whether a parallelogram with vertices u(2,−2), v(9,−2), w(9,−6), and x(2,−6) is a rectangle, rhombus, or square. give all the names that apply.

What is the name used to describe a graph where for some value of x, there exists 2 or more different values of y?

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.
