Triangle Proofs Playlist for Geometry
Now that we've gotten acquainted with proofs on a general basis, we jump into a major component of the Geometry curriculum: proofs specifically for triangles. As if we're secret agents with our own encrypted language, we learn about SSS, SAS, AAS, ASA, and CPCTC.
At the top of each video, you can access that lesson's worksheet and quiz.
The worksheet contains the exact problems we cover in the video. Just print the sheet and work along with the class.
Take the quiz right after the video, to see how well you learned it.
To access the worksheet and quiz at any time, simply pause the video.
Below, you also have the option of viewing the same playlist on YouTube.
