b. lines that meet at a 45° angle
c. lines that meet at a 90° angle
d. lines that are not in the same plane

Explanation:

Perpendicular lines are defined as lines that intersect at a right - angle, which is 90°. Option A describes parallel lines. Option B describes lines that form a 45 - degree angle, not perpendicular. Option D describes skew lines.
