Unit 4: Tremendous Triangles

Lesson 10 of 10

Lesson 10 of 10

## Objective: Students will show their knowledge of congruent triangles by creating a video of their own congruent proof and/or completing a jigsaw activity that reviews SSS, SAS, ASA, AAS and HL.

#### Student Exemplars

*5 min*

Here are two examples of students' work for this project.

The video below highlights what I considered to be a perfect project with strong explanations for the content, proving two triangles congruent, and also a clear explanation of strategies and tips for solving.

The second video has a mathematical error but is also very creative, and funny. These students were asked to re-write their triangle proof to earn credit back.
