Product Description
Similar Triangles Proofs Lesson Materials (Guided Notes, Classwork, & Homework):

These 6 student worksheets will help your students learn how to prove that two triangles are similar. These lesson materials include a 2-page set of guided notes, a 2-page classwork assignment, and a 2-page homework assignment, for a total of 6 student worksheets!

The guided notes include a vocabulary section, an example of a proof using corresponding angles and the reflexive property, and 2 examples of a proof using congruent right triangles and the reflexive property. All of the proofs are 4 or 5 steps long, and the triangles are always similar by Angle-Angle (AA) Similarity.

The classwork assignment includes proofs where students have to fill in only the reasons, proofs where students have to fill in a mixture of statements and reasons, and proofs where students have to fill in the entire proof.

The homework assignment includes the same 2 types of proofs. It includes proofs where students have to fill in a mixture of statements and reasons and proofs where students have to fill in the entire proof.

These proofs are designed to introduce students to easy similar triangle proofs in preparation for more difficult lessons, such as “Proving the Pythagorean Theorem using Similar Triangles” and “Proving the Triangle Proportionality Theorem.”

This set of practice worksheets comes with 2 pages of guided notes and 4 pages of proofs practice (1 classwork assignment and 1 homework assignment), answer keys, and a PowerPoint file containing pictures of the worksheets and keys. The worksheets in the PowerPoint are NOT editable. When you purchase this set of lesson materials, you will receive a pdf containing the guided notes, worksheets, and answer keys, and you will receive a PowerPoint file. Before purchasing this product, please review the preview file closely to make sure that these proofs are appropriate for your students.

Please Note: The classwork and homework worksheets included in this product are the exact same worksheets as the ones sold in my "practice worksheets" product. The difference between the two products is that the "lesson materials" come with guided notes. Choose to purchase either the "lesson materials" or the "practice worksheets," but do not purchase both.
