Week #November 30 - December 4
Unit of InstructionUnit 2B: Congruence of Proofs with Triangle Properties
Standard(s) Taught

MAFS.912.G-C.3.10:  Prove theorems about triangles; use theorems about triangles to solve problems. (Theorems include: measures of interior angles of a triangle sum to 180°; triangle inequality theorem; base angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of a triangle meet at a point.)

Learning Targets and Learning Criteria
  • classify triangles by sides and angles
  • prove theorems about triangles
  • solve problems using definitions, theorems, postulates about triangles, including: 

        a) Measure of interior angles of a triangle sum to 180 degrees

       b) Base angles of isosceles triangles are congruent

       c) An exterior angle of a triangle is equal to the sum of the measures of the remote interior angles

       d) Hinge Theorem

       e) The medians of a triangle meet at a point (centroid)

       f) The angle bisectors of a triangle meet at a point (incenter)

       g) The perpendicular bisectors of a triangle meet at a point (circumcenter)
