## 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.

(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!

Welcome to the Math Medic Geometry course! Here you will find a ready-to-be-taught lesson for every day of the school year, along with expert tips and questioning techniques to help the lesson be successful. Each lesson is designed to be taught in an Experience First, Formalize Later (EFFL) approach, in which students work in small groups on an engaging activity before the teacher formalizes the learning.

Our Geometry course develops reasoning, justification, and proof skills through an in-depth study of shapes and their properties, rigid transformations and congruence, and the relationship between similarity and right triangle trigonometry. Rich opportunities for problem solving culminate in the unit on surface area and volume. This course was created using the Common Core State Standards as a guide. The standards taught in each Math Medic Geometry lesson can be found here . Additionally, we've chosen to include a unit on Statistics and Probability that can be used as a stand-alone unit at any time during high school course work. The unit overviews and learning targets for the Math Medic Geometry course can be found here .

A triangle that has two of its sides congruent to each other is an isosceles triangle, and also, the angles opposite these congruent sides have equal angle measure. 12. Angle B is opposite to side AC, and angle A is opposite to CB. If AC is congruent to CB, therefore: m∠A = m∠B. Substitute.

13. Gina wilson all things algebra geometry unit 4 homework 3.

In a triangle, the sum of all three angles is always 180 degrees. Therefore, to find the value of the second angle when one angle is 29 degrees and the third angle is expressed as 11x - 65 degrees, we can set up the following equation: Angle 1 + Angle 2 + Angle 3 = 180. Given: Angle 1 = 29 degrees, Angle 3 = 11x - 65 degrees.
