question 8 of 10
if (overleftrightarrow{jk}perpoverleftrightarrow{lm}), which statement is true?
a. (overleftrightarrow{jk}) and (overleftrightarrow{lm}) are coplanar and do not intersect.
b. (overleftrightarrow{jk}) and (overleftrightarrow{lm}) meet at a straight angle.
c. (overleftrightarrow{jk}) and (overleftrightarrow{lm}) are not in the same plane.
d. (overleftrightarrow{jk}) and (overleftrightarrow{lm}) meet at a right angle.

Explanation:

The symbol $\perp$ means perpendicular. Perpendicular lines are in the same plane and meet at a right - angle (90 degrees). A straight angle is 180 degrees. Parallel lines are coplanar and do not intersect. Lines that are not in the same plane are skew.

Answer:

D. $\overleftrightarrow{JK}$ and $\overleftrightarrow{LM}$ meet at a right angle.
