Congruent Triangles Proofs with CPCTC Practice Worksheets (Classwork and Homework):
This set of classwork and homework assignments will help your students practice proving that triangles are congruent and that corresponding parts of congruent triangles are congruent (CPCTC). The majority of the proofs in these assignments involve proving that “base angles of isosceles triangles are congruent” and proving that “points on a perpendicular bisector of a line segment are exactly those equidistant from the segment’s endpoints.” These practice worksheets include a 2-page classwork assignment and a 2-page homework assignment, for a total of 4 pages of practice!
The classwork assignment includes proofs where students have to fill in only the reasons, proofs where students have to fill in a mixture of statements and reasons, and proofs where students have to fill in the entire proof. The classwork assignment has 6 proofs. Most of the proofs are 6 or 7 steps.
The homework assignment includes the same types of proofs as the classwork assignment. The last proof on this assignment is a more challenging proof. There are 6 proofs on the homework assignment, and the proofs range from 4 to 7 steps.
The “Reasons” used in these proofs are: Reflexive Property of Congruence, All right angles are congruent; Definition of Segment Bisector; Definition of Angle Bisector; AAS; ASA; SAS; CPCTC; Vertical angles are congruent; Definition of Perpendicular Lines; Each angle has one unique bisector; and If parallel lines are cut by a transversal, then alternate interior angles are congruent.
This set of practice worksheets comes with 4 pages of proofs practice (1 classwork assignment and 1 homework assignment), answer keys, and a PowerPoint file containing pictures of the worksheets and keys. The worksheets in the PowerPoint are NOT editable. When you purchase this set of practice worksheets, you will receive a pdf containing the worksheets and answer keys, and you will receive a PowerPoint file. Before purchasing this product, please review the preview file closely to make sure that these proofs are appropriate for your students.
