|Subject Area||Geometry Honors|
|Unit of Instruction||2(A): Triangle Congruence and Proofs|
|Learning Targets and Learning Criteria|
• draw transformations of reflections, rotations, translations, and combinations of these using graph paper, transparencies, and/or geometry software.
• describe and illustrate how a rectangle, parallelogram, and trapezoid are mapped onto themselves using transformations.
• define pre-image and image, and use correct notation (A vs. A’)
• draw a specific transformation when given a geometric figure and a rotation, reflection, or translation.
• define and use rigid motions as reflections, rotations, translations and combinations of these, all of which preserve distance and angle measure.
• identify corresponding sides and corresponding angles of congruent triangles.
• list the conditions to prove triangles are congruent.
• apply triangle congruence and triangle similarity to solve problems (e.g., indirect measure, missing sides/angle measures, side splitting).
