Learning Goal: Develop understanding and fluency with triangle congruence proofs.
- Estimation – 2 Rectangles
- Warm Up
- Why does SAS work? (Illustrative Mathematics)
- Why does SSS work? (Illustrative Mathematics)
- Maybe put both of these on coordinate plane or in Geogebra to help?
- Common Core
- G.6(B) – prove two triangles are congruent by applying the Side-Angle-Side, Angle-Side-Angle, Side-Side-Side, Angle-Angle-Side, and Hypotenuse-Leg congruence conditions
