A prior knowledge of triangle congruence postulates( SSS, SAS, ASA, AAS, and HL) is a prerequisite to work with the problems in this set of printable PDF worksheets. Congruent parts Implement this collection of pdf worksheets to introduce congruence of triangles.
Triangle congruence activity
This is an activity that uses both Desmos and Web Sketchpad. In the first part of the activity students investigate the nature of triangle congruency by using an external websketch to manipulate triangles. Once they discover all of the congruency rules then there are some practice problems which they can do to see if they understand them.
Triangle Congruence Proofs - SSS & SAS Postulates This worksheet contains problems and proofs that involve showing that two triangles are congruent using the SSS and SAS postulates. These proofs also require an understanding of previous properties,...
