We shared, added to, and practiced using C-17-20 from our last class.
We discovered two new conjectures about relationships among sides of triangles. We proved the Triangle Exterior Angle Theorem with a fill-in-the-blank two-column proof.
We added C-21-23 to our Geometric Truth (see attachment below) and practiced applying them in class by working with a partner on p 216-7:1-15.
There will be a short quiz over the last two blocks of content on our second block after Thanksgiving break (Block 11).
The test over triangles should be sometime close to the end of the week of December 5-9.
Students got to view their Transformation Test in class.
