We discussed this lesson today as a class:
If you were absent from today’s class, here are two videos that cover what was discussed.
First, here is a 5-minute discussion of what a proof consists of, and how to use Geogebra to build a complete proof:
Second, here is a video showing how to complete the first question from the opportunity to learn, focusing on how to properly build a right-triangle – one that remains accurate when vertices are moved around:
Opportunity to Learn
Complete the opportunity to learn listed on the second page of today’s lesson.
TIP
Due to the nature of a geometric proof, it’s not possible to provide final answers only.
We will take up these proofs in our next class – be sure to save your work and have it ready to compare to the examples that will be shared.
Completing this opportunity to learn will help you with next week’s in-class assignment.
