Asked by Jeremy

Martin wants to use coordinate geometry to prove that the opposite sides of a rectangle are congruent. He places parallelogram ABCD in the coordinate plane so that A is (0, 0), B is (a, 0), C is (a, b), and D is (0, b).

What formula can he use to determine the distance from point D to point A?


A.(0-0)^2+(b-0)^2=b^2
B.(a-a)^2+(b-0)=b^2
C.sqaure root of (a-a)^2+(b-0)^2=square root of b^2=b
D.square root of (0-0)^2+(b-0)^2=square root of b^2=b

A(0,0), B(a,0). AB is a hor. line, because Y is constant.
AB = a - 0 = a.

D(0,b), C(a,b). DC is a hor. line.
DC = a - 0 = a.

AB = DC, Because quantities that are =
to the same or = quantities are = to
each other.

A(0,0), D(0,b). AD is a Vertical line,
because X is constant.
AD = b - 0 = b.

B(a,0), C(a,b). BC is a vertical line,
because X is constant.
BC = b - 0 = b.

AD = BC, Because quantities that are =
to the same or = quantities are = to
each other.

The answer is D(square root of (0-0)^2+(b-0)^2=square root of b^2=b) just took a quiz with the same question.
