Complete the coordinate proof of the theorem.
Given: A B C D is a square. Prove: The diagonals of A B C D are perpendicular. Art: A square A B C D 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 vertices C and D are unlabeled. Diagonal A C and B D are drawn by dotted lines.

The coordinates of square ABCD are A(0, 0), B(a, 0), C(_, a), and D(0, _).
The slope of AC___ , when simplified, is equal to
.
The slope of BD___, when simplified, is equal to −1 .
The product of the slopes is equal to
.
Therefore, AC¯¯¯¯¯ is perpendicular to BD¯¯¯¯¯.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
