This is a set of 2 foldables designed for interactive math notebooks. Each foldable contains a definition and diagram of the Isosceles Triangle and Equilateral Triangle congruence theorems, the converse, as well as 2 different proofs using each theorem. There are also algebraic problems in the foldables using those theorems.
The answer keys are included!
I also have algebraic, segment, angle, SSS, SAS, ASA, and AAS proofs in my store. This set is also included in my growing Geometry Proof Bundle that is in my store!
