1st/2nd Honors Geometry Skinny

When

11/17/2022

Standards Addressed:
MGSE.9-12.G.CO.8 Explain how the criteria for triangle congruence (ASA, SAS, and SSS) follow from the definition of congruence in terms of rigid motions. (Extend to include HL and AAS.)
MGSE.9-12.G.SRT.5 Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.

Learning Targets/Success Criteria:
1. I can prove two triangles congruent using congruence theorems such as SSS, SAS, AAS, ASA, and HL.
--I can identify congruent and corresponding sides.
--I can identify included and non-included sides.
--I can identify included and non-included angles.
2. I can complete a formal two-column proof to prove two triangles congruent.
--I can list, identify and mark given statements on two triangles.
--I can identify and mark vertical angles, reflexive property, alternate interior angles, definition of a bisector, definition of a midpoint and provide a correspondence statement that verifies those marks.

Introduction/Connection (Activator): steps to triangle proofs.

Direct Instruction/Guided Practice:
--Guide students in completing cloze notes on Steps to Triangle Proofs
--Guide students in Triangle Congruence Proofs foldable (attached below).

Independent Practice/Collaboration/Differentiation:
--Differentiation: Foldable, cloze notes, graphic organizers, one-on-one assistance for struggling students, accelerated problems for more advanced students.
--Collaborative Practice: Students will work in collaborative pairs to complete Triangle Congruence Proofs book

Summarizer/CFU: TOTD.
