Product Description
Angle Pair Relationships –Notes & Intro to Proof

This reviews different angle pair relationships from grade 7 geometry:
Complementary Angles
Supplementary Angles
Vertical Angles
Linear Pairs

The lesson then continues to extend the vocabulary to key words for writing proofs, such as axiom, postulate, and theorem, followed by the angle addition postulate and segment addition postulate.

Practice Digital Drawing with linear pairs and vertical angles
Online exploration activities to discover that linear pairs form supplementary angles and that vertical angles have equal measure.

Students make conjectures based on the exploration followed by brainstorming how to prove their statement. Turn & talk to a neighbor to get the most brainstorming ideas.
Students are walked through their very first set of proofs!
The lesson ends with a quick formative self assessment recapping key aspects of the lesson.
Practice exercises give students the opportunity to distinguish between statements and reasons, better preparing them to write proofs.
Tip: use scrap paper or white boards for students to sketch figure on for processing or brainstorming.
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.
