Two lines that intersect to form right angles are known as?

• A. Orthogonal Lines
• B. Intersecting Lines
• C. Angle Bisectors
• D. Perpendicular Lines

Answer: (D)

Perpendicular lines are two lines that meet to form a right angle. The key idea is that the angle between them at their intersection is exactly 90 degrees, like the corner of a square. Intersecting lines just cross somewhere and don’t specify the angle, while angle bisectors are lines that split an existing angle into two equal parts. So the phrase that matches two lines forming a right angle is perpendicular lines.
