Explore how lines of symmetry help define different categories of quadrilaterals. Looking at a square, rectangle, trapezoid, and parallelogram, young mathematicians discover that each shape has its own, unique symmetry. Encourage your class to look for patterns between the angles and side lengths of each shape and the lines of symmetry they found. A great resource for developing a deeper understanding of quadrilaterals.
