This lesson is on pages 145-148 of Jacob's Geometry
SSS Theorem if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
Look at this interactive tutorial
It shows how two triangles remain congruent, even if their dimensions are changes, so long as they are all changed together.
Here's a worksheet that shows the congruency symbols which are good to know about (the teacher in the video from a couple of days ago showed the symbols, too)
Here are a couple of SSS Proofs
Do:
- Set I, 1-6,
- Set II, odd numbers
