In this activity, students will discover the properties of a parallelogram. Students will measure various components of a parallelogram to make conjectures about its properties.
Before the Activity
Download the TNS file and make it available to students.
Students need to be familiar with the following terms: alternate interior angles, bisect, opposite angles, opposite sides, parallel lines, and slope.
This activity can be used as an introduction to the properties of a parallelogram or as a refresher for proofs involving parallelograms.
During the Activity
This activity is teacher-led.
Emphasize the importance of students not working ahead. Otherwise, it may be difficult to troubleshoot their errors.
It is sometimes helpful for students to work with a partner.
