Here are the parallel and perpendicular lines identified from the graph:
Parallel Lines:
- AB∥PQ
- AB∥UV
- AB∥MN
- PQ∥UV
- PQ∥MN
- UV∥MN
- ST∥GH
Perpendicular Lines:
- UV⊥XY (Vertical line UV intersects horizontal line XY at point X, forming a 90∘ angle.)
- ST⊥EF (Line ST has a slope of 1, and line EF has a slope of −1. Since the product of their slopes is −1, they are perpendicular.)
- GH⊥EF (Line GH has a slope of 1, and line EF has a slope of −1. Since the product of their slopes is −1, they are perpendicular.)
