GSE Analytic Geometry-A
Week 8: 2/20/2017 – 2/24/2017
Georgia Performance Standards:
• know that rigid transformations preserve size and shape or distance and angle; use this fact to connect the idea of congruency and
develop the definition of congruent
• use the definition of congruence, based on rigid motion, to show two triangles are congruent if and only if their corresponding sides
and corresponding angles are congruent
• use the definition of congruence, based on rigid motion, to develop and explain the triangle congruence criteria; ASA, SSS, and SAS
• prove theorems pertaining to lines and angles
• prove theorems pertaining to triangles
Standards for Mathematical Practice:
1. Make sense of problems and persevere in solving
them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the
reasoning of others.
4.
5.
6.
7.
8.
Model with mathematics.
Use appropriate tools strategically.
Attend to precision.
Look for and make use of structure.
Look for and express regularity in repeated reasoning
