Complete the coordinate proof of the theorem.
Given: A B C D is a rectangle. Prove: The diagonals of A B C D are congruent. Art: A rectangle is graphed on a coordinate plane. The horizontal x-axis and vertical y-axis are solid. The vertex labeled as A lies on begin ordered pair 0 comma 0 end ordered pair. The vertex labeled as B lies on begin ordered pair a comma 0 end ordered pair. The vertex labeled as D lies on begin ordered pair 0 comma b end ordered pair. The vertex C is unlabeled. Diagonals A C and B D are drawn by dotted lines.
Enter your answers in the boxes.
The coordinates of rectangle ABCD are A(0, 0), B(a, 0), C(
,
), and D(0, b).
The length of AC¯¯¯¯¯ is equal to
.
The length of BD¯¯¯¯¯ is equal to
.
The diagonals of the rectangle have the same length.
Therefore, AC¯¯¯¯¯ is congruent to BD¯¯¯¯¯.

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?
