If three corresponding pairs of sides of two triangles are congruent, the triangles are congruent.
Sometimes that is called the side-side-side theorem. Put that in the right hand column. This looks like a one-step proof to me.
It has been a long time since I did two-column proofs
I have no idea where to start! and I've got lots of these to write.
Directions say write a two-column proof...
Given: segment AB is congruent to segment XY, AC is is congruent to XZ, and BC is congruent to YZ.
Prove: triangle ABC is congruent to triangle XYZ
