Geometry Instructional Unit

by

Alison Hays

This unit is an introduction to geometry. I plan to use it with a Technical Mathematics II class. I expect some of the lessons, especially lessons 1 and 3, to take more than one day. This unit will definitely last 10 days.

Lesson 1: Introduction to Geometry and GSP

Lesson 2: Angles

Lesson 3: Parallel Lines

Lesson 4: Triangles

Lesson 5: Polygons and Parallelograms

Lesson 6: Rhombuses

Lesson 7: Rectangles and Squares

Lesson 8: Trapezoids

This unit is adapted from Chapter 4 of the book *Algebra One
Interactions* published by Holt, Rinehart, and Winston.
