The coordinates of square abcd are a(0, 0) , b(a, 0) , c(blank, a), and d(0,blank ). the slope of ac, when simplified, is equal to blank . the slope of bd, when simplified, is equal to −1 . the product of the slopes is equal to blank . therefore, ac is perpendicular to bd. fill in the blank spots

This is about finding slopes of lines.

The slope of AC, when simplified = 1

The product of the slopes = -1

ABCD is a square.

All sides of a square are equal.

This means that;

If AB = a, then it means;

AB = BC = CD = AD = a

Point D is on the y-axis and so coordinate of D is; (0, a)

While coordinate of C is; (a, a)

Thus coordinates of each point of the square are;

A(0, 0) , B(a, 0) , C(a, a) and D(0, a)

Formula for slope between two coordinates is; m = (y2 - y1)/(x2 - x1)

Thus;

The slope of AC = (a - 0)/(a - 0) = a/a = 1The slope of BD, when simplified, is equal to −1The product of the slopes of AC and BD = 1 × (-1) = -1Therefore, AC is perpendicular to BD.:

The coordinates of square ABCD are A(0, 0) , B(a, 0) , C(blank, a), and D(0,blank ).

square, all sides are equal so side = a
A(0, 0) , B(a, 0) , C(a, a), and D(0,a).

The slope of AC = (a-0)/(a-0) = a/a = 1
The slope of BD, when simplified, is equal to −1

The product of the slopes = 1(-1) = -1

Therefore, AC is perpendicular to BD.
