Geometry Concepts and Applications

This video tutorial from Math Sucks is designed to help students pass the geometry Common Core Regents exam. It covers three main questions: calculating the minimum degrees needed to rotate a regular pentagon onto itself, identifying transformations between congruent triangles, and solving a right triangle trigonometry problem. The video provides step-by-step solutions and encourages viewers to explore additional resources for further practice.
