Understanding Polygons and Their Properties

Miss Hamilton introduces polygons, focusing on their characteristics, such as having straight sides and being closed figures. She explains vertices and edges, and discusses quadrilaterals and trapezoids. The video emphasizes finding the area of polygons by decomposing them into rectangles and triangles, using examples to illustrate the process.
