Exercise 6 Page 803

Consider the Perpendicular Transversal Converse Theorem.

True

Practice makes perfect

Let's analyze the given figure. We know that AD⊥l and ABCDEFGH is a cube.

Since ABCDEFGH is a cube, we also know that AD is perpendicular to DC. Besides that AD, DC, and line l lie in plane M.

Therefore, by the Converse Perpendicular Transversal Theorem, the statement is true.
