Parallel Lines and Angles
by Anonymous
Tilt the transversal to compare corresponding and alternate angles, and see which ones change once the lines stop being parallel.

About this app
An interactive middle-school geometry app for exploring angle relationships formed by two lines and a transversal. Learn to identify vertical, corresponding, alternate, and co-interior angles, then tilt the lines to see which relationships depend on parallelism. A challenge mode provides angle-calculation questions using equality and supplementary-angle rules.
Use cases
- Middle-school students learning parallel lines and angles
- Teachers demonstrating transversal angle relationships
- Learners practicing angle calculations interactively
- Classroom review of geometry vocabulary and rules
Features
- Highlights pairs of vertical, corresponding, alternate, and co-interior angles
- Adjusts the transversal angle and the lower line’s tilt
- Shows how non-parallel lines affect corresponding and alternate angles
- Demonstrates that co-interior angles sum to 180° when lines are parallel
- Includes four-step challenge questions with score and streak tracking
- Provides reset and next-pair controls
