Is the following definition of perpendicular reversible? If yes, write it as a true biconditional.
Two lines that intersect at right angles are perpendicular.

a. The statement is not reversible
b. Yes; if two lines intersect at right angles, then they are perpendicular.
c. Yes; if two lines are perpendicular, then they intersect at right angles.
d. Yes; two lines intersect at right angles if(and only if) they are perpendicular.

Answer 1
