Question

4. Is the following definition of perpendicular reversible? If yes, write it as a true biconditional.

Answer 1

Answer:

Yes; two lines intersect at right angles if (and only if) they are perpendicular.

Step-by-step explanation:

In a biconditional statement, both parts have to be true. In this case, if the two lines intersect at a right angle then they are perpendicular, and if they are perpendicular then they intersect at a right angle

Answer 2

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.

Your Answer would be (D)

Yes; two lines intersect at right angles if (and only if) they are perpendicular.
