Proving Triangles Congruent Proof Activity - High School Geometry Proofs

Printable PDF & Digital Versions are included in this distance learning ready activity which consists of 6 cut & paste Triangle Congruency Proofs. This fun & engaging activity will strengthen your students’ skills in solving proofs involving proving triangles congruent & the triangle congruence theorems (SAS, ASA, AAS, SSS, & HL).

Easily Differentiate with 2 Included Version

• Version A has student sort both the statements and reasons.
• Version B has students only sort the reasons to the matching statement (which is printed on the proof).

Both versions can be used at the same time for easy differentiated instruction in a mixed abilities classroom.

Distance learning? No problem! This activity now includes a Google Slides digital option in addition to a PDF printable option.
