- Google Apps™

## What educators are saying

Also included in.

## Description

This Similar Triangles Unit Bundle contains guided notes, homework assignments, two quizzes, a study guide and a unit test that cover the following topics:

• Ratio and Proportion: Includes extended ratio problems.

• Similar Figures: Identifying scale factors, and solving problems with similar figures using scale factors and proportions

• Proving Triangles Similar: Angle-Angle, Side-Side-Side, and Side-Angle-Side Similarity.

• Direct Similar Triangle Proofs

• Parallel Lines and Proportional Parts

• Parts of Similar Triangles: Altitudes, Angle Bisectors, and Medians

• Triangle Angle Bisector Theorem

ADDITIONAL COMPONENTS INCLUDED:

(1) Links to Instructional Videos: Links to videos of each lesson in the unit are included. Videos were created by fellow teachers for their students using the guided notes and shared in March 2020 when schools closed with no notice. Please watch through first before sharing with your students. Many teachers still use these in emergency substitute situations. (2) Editable Assessments: Editable versions of each quiz and the unit test are included. PowerPoint is required to edit these files. Individual problems can be changed to create multiple versions of the assessment. The layout of the assessment itself is not editable. If your Equation Editor is incompatible with mine (I use MathType), simply delete my equation and insert your own.

(3) Google Slides Version of the PDF: The second page of the Video links document contains a link to a Google Slides version of the PDF. Each page is set to the background in Google Slides. There are no text boxes; this is the PDF in Google Slides. I am unable to do text boxes at this time but hope this saves you a step if you wish to use it in Slides instead!

Best Geometry curriculum ever! So very well put together. My student loved it and says she only wants to use resources from this vendor for her math classes.

I always look at All Things Algebra first when I need additional practice or supportive resources for my students. These products are so well organized, thorough, and can be used in a variety of ways. I truly appreciate this work!

Absolutely love how these units are organized and laid out. I wish I could afford to buy them all at once, but buying them one at a time works for my monthly budget. My students appreciate how thorough the notes are and how the examples match throughout the unit.
