Question

what lines are perpendicular
line sr & line su
line pn and line pq
line sp & line pq
line sp & line rq

Explanation:

Step1: Recall perpendicular - lines definition

Perpendicular lines intersect at a 90 - degree angle.

Step2: Analyze each option

• For "line SR & line SU": They form a right - angle at point S.
• For "line PN and line PQ": They do not form a right - angle.
• For "line SP & line RQ": They are parallel, not perpendicular.
• For "line SP & line PQ": They form a right - angle at point P.

Answer:

line SR & line SU, line SP & line PQ
