Prisms, Angles, and Area Concepts

This video by Mr. Lima is a workshop aimed at helping seventh-grade students review key math concepts related to angles, areas, and volumes. It covers types of angles, such as supplementary, complementary, vertical, and right angles, and provides practice problems to reinforce understanding. The video also explains how to calculate the area of two-dimensional figures like trapezoids and triangles, as well as the volume and surface area of three-dimensional prisms. The content is designed as a review for students who are preparing for assessments, with a focus on practical problem-solving techniques.
