# Parallel Lines Cut by a Transversal

##### This Parallel Lines Cut by a Transversal handout & reference 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.

CCSS: Designed

##### 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
