Properties and Relationships of Shapes

This lesson focuses on classifying two-dimensional figures, specifically rectangles and rhombuses. It explains the properties of these shapes, such as the equal sides of a rhombus and the right angles of a rectangle. The lesson includes drawing exercises for both shapes and a calculation of a rhombus's side length from its perimeter. Students are encouraged to use GeoGebra to explore the properties of these quadrilaterals dynamically.
