# Q2, W4: November 30 – December 4 Geometry

Teacher Kristin Andreason Geometry Honors 8 November 30 - December 4 Unit 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
• 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)
