    Learning Goals:

    • Quadrilaterals are closed shapes/polygons that have exactly 4 sides 
    • Squares have 4 equal sides and 4 right angles/square corners 
    • A rhombus has 4 equal sides, NOT 4 right angles/square corners 
    • Rectangles are not squares because they have opposite equal sides rather than 4 equal sides.
