Unit of InstructionUnit 2A and Unit 2B
Standard(s) Taught

MAFS.912.G-SRT.2.5:  Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.

MAFS.912.G-CO.3.10:  Prove theorems about triangles to solve problems.  Theorems include: triangle angle sum theorem, triangle inequality theorem, etc.

Learning Targets and Learning Criteria
  • Students will be able to identify the congruent parts of two triangles
  • Students will be able to determine whether or not two triangles are congruent by the Triangle Congruence Postulates (SSS, SAS, ASA, AAS, and HL)
  • Students will be able to construct a proving using triangle theorems, triangle concgruence postulates, and Corresponding Parts of Congruent Triangles Are Congruent.
  • Students will learn the Triangle Inequality Theorem and be able to determine if three side measures can be a triangle.
Classroom Activities

Monday/Tuesday:

  • Students will create p. 17 in their ISN on “Corresponding Parts of Congruent Triangles are Congruent:
  • Students will do a group activity on proofs, filling in the missing statements and reasons and gluing them in the appropriate spaces.

Wednesday:

  • Students will finish and check their proof activity

Thursday/Friday:

  • Students will do another proof activity where they must create the entire proof using statements and reasons that are provided for three proofs
  • Students will take notes on Triangle Inequality Theorem (p. 18 in ISN)
Assignments Due
  • Group proof activity due October 24
  • Second proof activity due October 25/26
