Understanding Slope, Pythagorean Theorem, and Exponents

This lesson focuses on finding unknown side lengths in right triangles using equations. It covers identifying hypotenuses, solving for unknown sides, handling fractional side lengths, and working with composite figures. The lesson concludes with a summary and homework problems to reinforce the concepts.
