Geometry Concepts and Problem Solving

Mrs. Black Beckler provides a tutorial on solving geometry problems from page 404, focusing on problems 17, 18, 31, and 32. She explains the use of chord theorems and the Pythagorean theorem to solve these problems, emphasizing the importance of understanding the geometric properties involved. The video includes detailed solutions for problems 17 and 18, and offers guidance for problems 31 and 32, encouraging students to apply the learned concepts independently.
