Exploring 8th Grade Math: Chapter 12 Review

This video is a review of Chapter 12, focusing on the Pythagorean theorem and the distance formula. It provides practice problems for students to solve, covering the use of the Pythagorean theorem in 2D and 3D, the converse of the theorem, and finding distances on a grid using both the theorem and the distance formula. Students are encouraged to check their work and use their notes and previous videos for additional review.
