40 Proofs in MS Word. Proofs cover SSS, SAS, ASA, ASA, HL, AAS, CPCTC, equidistant theorem, parallel lines, circles, overlapping triangles, and more All proofs can be easily manipulated to prove other parts of the diagram. I assign one proof every 3 days to keep the format and structure in my students minds. All proofs are two columns. Proofs range from 6-14 steps.
