Students will work on filling out these triangle congruence proofs. This sheet offers a variety of triangle congruence to include SSS, SAS, AAS, ASA, and HL.

Proportions and similarity circuit focuses on setting up and solving proportions to prove similarity between two triangles. Some problems also include calculating scale factor and or solving for x, in order to prove similarity. A circuit worksheet is an efficient way for students to self-check their work when practicing.

This proofs progression worksheet helps build a students skill it forming a proof about triangle congruence. The table will have student observe what is given, decide on new information, and decide what type of triangle congruence occurred. From here students should be able to transfer their information into a two column proofs.

Students solve for missing interior and exterior angles in twelve triangle problems. Some problems have students solve for the x-value first, and then plug their answer in to solve for the angle.

Students will work on understanding proofs involving SSS, SAS, AAS, ASA, and HL. Included is a proofs progression sheet to get students thinking on what needs to be included in the proof. After filling out the proofs progression sheet, students should be able to transfer over their information into the two-column proof.

Students will solve a variety of equilateral and isosceles triangle on this circuit worksheet. A circuit is a great way for students to self check their answers, and adds a twist to an everyday worksheet.

Student practice working on algebraic reasoning in preparation for proofs. They will cut and past the steps as well as the justification for each algebraic problem to solve for x.
