Product Description
Algebra meets Geometry

Order of operations are reviewed and then used to solve unknown angle problems. Students are asked to justify their steps while solving, which is a good introduction to writing proofs.

Pre-requisite skills:
Definition of Supplementary Angles; Vertical angles have equal measure; linear pairs are supplementary.
This lesson reviews solving algebraic equations from Algebra with a slight twist. Students are asked to justify each step for solving the equation with a property of equality.
The lesson continues to introduce the reflexive, symmetric and transitive properties of equality.
Finally, students combine their algebra and geometry skills to solve for unknown angle measures.
The lesson ends with a quick self assessment followed by practice problems to solve for missing angle measures.
Note: Lesson format is compatible with Google slides®

If you would not like your students to have the answers to grade as they go, simply delete those slides before sharing the file with your students.
