learning about two column proofs and triangles
If PQ is congruent to QS and QS is congruent to ST, then PQ equals ST.
I am doing geometry and we are studying proofs. Why do we need proofs in geometry? What purpose do they serve in geometry?
how do you do two-Column proofs well?
This is a proof or a disproof with a salvage.
