SWBAT: To use triangle congruence and CPCTC to prove that parts of two triangles are congruent. You Try It! A diagram in a proof sometimes requires lines, rays, or segments that do not appear in the original figure. These additions to diagrams are auxiliary lines. Ex 1: Consider the following problem. Theorem: All radii of a circle are congruent!

Using CPCTC with Triangle Congruence Period ______ 1. Fill in the missing statements and reasons. Given: AB || DC , ∠B ≅ ∠D Prove: BC ≅ DA D

ame: Geometry Triangle Congruence Proofs – CPCTC Date: Write a two Column Proof.

Corresponding Parts of Congruent Triangles are Congruent (CPCTC) is useful in proofs. If you prove that two triangles are congruent, then you can use CPCTC as a justification for proving corresponding parts congruent. SLO: I can prove parts of triangles are congruent through CPCTC.

PROOFS using CPCTC For #1-4, name the congruent triangles that contain the given corresponding congruent parts. Draw and label the triangles so that they do not overlap. In some cases there may be more than one pair of congruent triangles that contain the given corresponding congruent parts. 1.

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent and is used to justify two triangles are congruent in a proof. A and B are the endpoints of a bridge going over a river. What is the length of the bridge? Given YW bisects …

This CPCTC Proofs Worksheet helps students first prove triangles congruent by SSS, SAS, AAS, or ASA, and then prove corresponding parts of triangles (sides or angles) congruent by CPCTC.
