Math in a Box: Lessons for Algebra, Geometry and Precalculus
This is my new Math in A Box. I'm posting math lessons-examples/diagrams-for algebra geometry, trig, precalculus. Need help? Make requests as I have hundreds! Hopefully I can post enough to help parents new (or not) to homeshooling during the covid-19 pandemic.
Triangle TRS is Isosceles, and M is midpoint of TS and N is midpoint of TR.
Triangle TMR is congruent to triangle TNS or triangle SNT or both?
Can you trace the other pairs of triangles that are congruent?
You must also know how to NAME them too.
Why is triangle TMR not congruent to triangle SNT that I mentioned above?
