Geometry of Shapes: QuadrilateralsGrade Level: 9th – 10th Grade (High School Geometry)Description: An in-depth look at the properties of Quadrilaterals. It defines and lists theorems for Parallelograms, Rectangles, Rhombi, Squares, and Trapezoids (including Isosceles Trapezoids).How to Use: Use as a Reference Lecture. Each slide lists the specific properties (e.g., "Diagonals bisect each other") for a specific shape. Have students create a "Family Tree" of quadrilaterals in their notes as you go
