PRODUCT DESCRIPTION

This activity help students hone their skills with parallel lines. Students must determine if 2 lines are parallel based on the angles not the appearance of the lines. Some lines appear to be parallel but are not and others appear not parallel but should be.

Student sort the cards into 3 categories:
- Parallel
- Not Parallel
- Not enough information (can’t be determine)

This activity has 3 levels.
Level 1
• 9 cards
• 3 for each category
• Short/Quick Check for understanding.

Level 2
• 16 cards
• 8 Parallel/4 Not parallel/ 4 Not enough information.
• Great for small group learning.

Level 3
• 16 cards
• 6 Parallel/ 6 Not Parallel/4 Not enough information.
• Includes several challenging problems: the angles are not a special named angle. Students must use both linear pairs & corresponding angles to decide.

Note all levels have different cards so you can use each set with the same students.

How to use this sort:
Have students group in pairs or trios, give students a set of cards. Students sort cards into the three categories. There is a student response page to make grading easier.

Information needed to sort cards:

You can prove 2 lines are parallel if you can show any of the following:
- The corresponding angles are congruent.
- The alternate interior angles are congruent.
- The alternate exterior angles are congruent.
- The consecutive interior angles are supplements.
- The consecutive exterior angles are supplements.
- 2 lines are perpendicular to the same line
