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

All sides of a square are equal.

This means that;

If AB = a, then it means;

AB = BC = CD = AD = 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)

Thus;
