This self-grading digital assignment provides students with practice proving that two triangles are similar using the Angle-Angle Similarity Postulate, Side-Angle-Side Similarity Theorem, and Side-Side-Side Similarity Theorem. The last 3 questions also require students to find the missing value included in a side length. These questions require proportional reasoning and solving quadratics.

Question types include: "multiple-choice" and "short- response".

TpT will automatically add this form & file to your drive. You will also receive a PDF document that includes the exact same questions as the Google Form.

I use these assignments as class work or homework. I usually print the PDF for students to use before or while they complete the form. They are then allowed to use this form to make correction on questions they got wrong and turn in to me for partial credit back.

This assignment is included in the following bundles:
