geometry unit 4 homework 1

Description

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

• Classifying Triangles by Sides and Angles

• Angles of Triangles: Triangle Angle Sum Theorem and Exterior Angle Theorem

• Isosceles and Equilateral Triangles

• Triangle Congruence: SSS and SAS

• Triangle Congruence: ASA and AAS

• Right Triangle Congruence: HL

• Mixed Review of Triangle Congruence

• Corresponding Parts of Congruent Triangles are Congruent (CPCTC)

Please download the preview to see a sample outline along with a collage of some of the pages.

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!

geometry unit 4 homework 1

Geo.1 Constructions and Rigid Transformations

In this unit, students first informally explore geometric properties using straightedge and compass constructions. This allows them to build conjectures and observations before formally defining rotations, reflections, and translations. In middle school, students studied transformations of figures in the coordinate plane. In this unit, they transition to more formal definitions that don't rely on the coordinate plane, and the focus shifts from transforming whole figures towards a more point-by-point analysis. Students then begin to use the rigorous definitions they developed to prove statements involving angles and distances, preparing them for congruence proofs in the next unit.

A blank reference chart is provided for students, and a completed reference chart for teachers. The purpose of the reference chart is to be a resource for students to reference as they make formal arguments. Students will continue adding to it throughout the course. Refer to About These Materials  in the Geometry course for more information.

What format are the files in, will i have access to materials if they are updated, are answer keys included, are videos included.

I love this resource and can't wait to purchase the activity bundle to go with it! It is so well organized and my students have really benefited from the notes. I especially appreciate how clear the notes for writing proofs are. This is such a difficult skill and the author really breaks it down so simply. Thank you for this product!

-REBECCA P.

This is the 2rd Bundle I've bought from Gina with All things Algebra, and I cannot express how much these curriculum have changed my life (both personally and professionally). I teach at a school where the subject that I teach changes from semester to semester. Any and all high school math is fair game to assign me. The units are put together in an organized way and I can spend more of my time working to differentiate instruction, work with students, and find engaging supplemental activities to go along with the material (although I use the Activities Bundles that are an option to purchase all the time). instead of learning and creating a new curriculum from scratch every time they give me a new subject. I have more time at home with my family because of this resource. I actually enjoy teaching more than I ever have after that weight was lifted. I am eternally grateful.

-MICHELLE H.

My students love using this resource! This resource has replaced the current curriculum that I use in my classroom. The students love how to notes include practice problems and they love watching the videos when they are absent or need a refresher. HIGHLY RECOMMEND THIS PRODUCT! Geometry teachers, this resource eliminates the need to plan. Buy it now!
