This Parallel Lines Cut by a Transversal handout also includes:
Pupils study angle measurements between different types of angles associated with parallel lines and transversals. The independent practice asks pupils to identify the types of angles in a diagram and to determine the measure of angles.

Instructional Ideas
- Use the video as the homework portion in a flipped classroom environment
- Have the pupils determine other relationships between angles formed, such as which angles are supplementary
Classroom Considerations
- Individuals that have difficulty with spatial relationships many times have problems identifying the types of angles associated with parallel lines and transversals
- The types of angles exist even if the lines are not parallel; the parallel lines determine the measurements
- The lesson is the tenth installment of an 11-part unit on congruence and similarity
Pros
- Provides definitions of types of angles associated with parallel lines and transversals
- The diagrams in the homework provide the parallel lines in different orientations
Cons
- The lesson relies only on direct instruction to deliver the material
