Relationships in Triangles (Geometry Curriculum - Unit 5) | All Things Algebra®

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

• Midsegments of Triangles (includes reinforcement of parallel lines)

• Perpendicular Bisectors and Angle Bisectors

• Circumcenter and Incenter

• Medians Centroid

• Altitudes and Orthocenter

• Naming and Identifying a Center
• Construction Centers of Triangles

• Centers of Triangles on the Coordinate Plane

• Inequalities in Triangles: Determine if three sides can form a triangle.

• Inequalities in Triangles: Find the range of the third side length of a triangle given two side lengths.

• Inequalities in Triangles: Order angles given sides and order sides given angles.

• Inequalities in Two Triangles (Hinge Theorem)

• Triangle Inequalities with Algebra

Refresher notes on the Pythagorean Theorem also included as it is required with many of the centers problems. 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!
