Special Triangle Relationships Unit – High School Geometry Curriculum

A no-prep, fully guided unit on special triangle relationships for high school geometry (Geometry Unit 5). It combines warm-ups, guided notes, practice worksheets, activities, exit tickets, quizzes and a study guide.

Topics covered

• Triangle midsegments
• Bisectors
• Medians
• Altitudes
• Indirect proofs

How the unit works

Structured spiral warm-ups and exit tickets (bell ringers) run daily and keep students focused. For each lesson, students take guided notes that pair step-by-step explanations with fill-in-the-blank sections. The notes simplify the concepts with visual aids, clear definitions and practical examples, and filling them in keeps students organized and working with the material.

Multiple practice worksheets follow for independent practice and skill reinforcement. Station-appropriate activities, mazes and formative assessments check for understanding at every step.

For planning, you get a pacing calendar, detailed outlines and other planning resources. The editable version lets you customize the unit for your needs.
