Understanding quadrilaterals is important for getting good at geometry. Here’s why:

1. Basic Shapes: Quadrilaterals are shapes that have four sides. They include common shapes like squares, rectangles, and trapezoids. Learning about these shapes helps when solving geometry problems.

2. Key Features:

   • Parallelograms: These have opposite sides that are both equal and run parallel to each other.
   • Rectangles: In rectangles, all four angles are $90^\circ$.
   • Rhombuses: All sides of a rhombus are equal in length, but the angles can be different.

3. Real-life Uses: Quadrilaterals are everywhere! They are important in things like building designs and art.

By learning these features, Year 7 students can build a strong foundation in geometry.
