Unit 3 CA Standards
A “T” represents this unit and any questions related to triangles will be entered into the grade book under “T.”
2.0 Students write geometric proofs, including proofs by contradiction.
4.0 Students prove basic theorems involving congruence and similarity.
5.0 Students prove that triangles are congruent or similar, and they are able to use the concept of corresponding parts of congruent triangles. (2)
6.0 Students know and are able to use the triangle inequality theorem. (2)
12.0 Students find and use measures of sides and of interior and exterior angles of triangles and polygons to classify figures and solve problems. (3)
16.0 Students perform basic constructions with a straightedge and compass, such as angle bisectors, perpendicular bisectors, and the line parallel to
a given line through a point off the line.
