Two lines that intersect to form right angles are called

• A. Parallel lines
• B. Perpendicular lines
• C. Skew lines
• D. Horizontal lines

Answer: (B)

Two lines that cross and form a right angle are perpendicular. Perpendicular means the meeting angle is 90 degrees, like the corner of a square or a doorway frame. This distinguishes them from other kinds of lines: parallel lines never meet, skew lines don’t lie in the same plane and don’t intersect, and horizontal lines simply describe left-to-right direction. So the term that fits is perpendicular lines.
