ACT Spotlight
Essential Question: How do we know when two triangles are congruent? How can we prove congruence?
OAS Standard(s) Covered: G.2D.1.9 Construct logical arguments to prove triangle congruence (SSS, SAS, ASA, AAS and HL).
Informal Knowledge Check Post-Lesson: How can you determine which angles are the vertex angle and base angles of an isosceles triangle?
Informal Knowledge Check Post-Lesson: What is the difference in the information required to use SSS or SAS?
Informal Knowledge Check Post-Lesson: If both AAS and ASA require two angles and one side, how are they different?
Informal Knowledge Check Post-Lesson: When you write a proof, what kind of angles can you call congruent without having the information given?
Informal Knowledge Check Post-Lesson: What does the squiggle over an equal sign mean? What does ABC = DEF tell us (try to list all six things)?
