City Transfers: Angle Audit

Use angle relationships to check a bus and subway trip planner.

Triangular Route Loops

These questions concern a trip planner's map drawings, not travel times. A triangular route loop has three straight sides. An exterior angle is formed by extending one side beyond a vertex.

A bus route and two subway segments outline a triangle. The exterior angle at Junction is adjacent to its interior angle.
