Triangle Congruence Proofs Task Cards

In this set of task cards, students will write triangle congruence proofs.

Proof Justifications Used:

ASA - SAS - HL - SSS - AAS - Algebraic Properties of Equality - Vertical Angle Congruence Theorem - Parallel Lines Theorems and Converse Theorems- Definition of Angle Bisector - Definition of Segment Bisector - CPCTC - Base Angles Theorem and Converse - Definition of Isosceles Triangle - Definition of Right Triangle - Definition of Perpendicular Lines - Linear Pair Postulate - Congruent Supplements Theorem - Definition of Midpoint

Three versions of the task cards are given: fill in the blank (students only need to justify), fill in the blank (students must write the whole proof), and completely blank. A student answer sheet and answer key are included. The problems are of various difficulty. Make sure these problems are appropriate for your students - download the preview and look at the thumbnails to see problem examples. All of the proofs in the set are shown in the preview. This set includes 14 task cards and the solutions. Ideas for use are included.

Task cards are a great way to help students review or to use as warm-ups throughout the unit.
