and Congruence
Course:
Geometry MOD B
Dates:
Apr 13 – Apr 17, 2015
What are we learning?
Daily Objective:

The student will be able to understand the concept of congruent figures.
TEKS/AP/Standards:
Ⓡ GEOM.2B Make conjectures about angles, lines, polygons, circles, and three-dimensional
figures and determine the validity of the conjectures, choosing from a variety of
approaches such as coordinate, transformational, or axiomatic.
Ⓢ GEOM.3D Use inductive reasoning by collecting information and finding patterns to
formulate conjectures.
Ⓢ GEOM.3E Use deductive reasoning to prove a statement.
How will we learn it?

What are we learning?
TEKS/AP/Standards:
GEOM.1A Develop an awareness of the structure of a mathematical system, connecting
definitions, postulates, logical reasoning, and theorems to verify statements.
Ⓡ GEOM.3C Use logical reasoning and several methods of proof (flow proofs, transformation
proofs, coordinate proofs, and two-column proofs) to prove statements are true, and find
counter- examples to disprove statements that are false.
