Complete the explanation to determine whether each statement is always, sometimes, or never true. If quadrilateral PQRS is a rhombus and one diagonal has a slope of 4, then the other diagonal has a slope of
1/4 .
The diagonals of a rhombus are , so the product of the slopes of the diagonals is . Therefore, the diagonals of a rhombus have slopes of 4 and
1/4 , since 4 · 1/4 −1. The statement is true.
