Resources in High School Geometry explore the properties of angles, shapes, and figures in space. Angles are analyzed using pool balls in an interactive lesson and video, students can discover how using concentric circles can help determine how much paint is needed to cover the deck of a carousel, and volume is analyzed through experiments with popcorn and meatballs. Students will model architectural concepts, find the area of a variety of shapes, and study Sophie Germain and her pursuit of her mathematical passion with resources in High School Geometry.
