Triangles Playlist for Geometry
Now, we bring all the wisdom we gained from previous playlists to this culminating one, on triangles. We discuss angles, sides, isosceles, and play around with creating triangles. Then we move onto a fundamental component of Geometry, which also appears on the SAT, ACT, and even the GRE: the 30-60-90 and 45-45-90 triangles. They're presented in the Math Bobby costume, fun!
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.
