Quadrilaterals

A quadrilateral is a polygon with four sides. The sum of the interior angles of a quadrilateral is always 360 degrees. There are different types of quadrilaterals, each with its own unique characteristics.

Types of Quadrilaterals

1. Rectangle: A quadrilateral with four right angles. Opposite sides are parallel and equal in length.
2. Square: A special type of rectangle with all sides of equal length.
3. Parallelogram: A quadrilateral with opposite sides that are parallel and equal in length.
4. Rhombus: A parallelogram with all sides of equal length.
5. Trapezoid: A quadrilateral with one pair of parallel sides.

Study Guide

Here are some key points to remember about quadrilaterals:

• Quadrilaterals have four sides and four angles.
• The sum of the interior angles of a quadrilateral is always 360 degrees.
• Rectangles have four right angles and opposite sides that are equal in length and parallel.
• Squares are special rectangles with all sides of equal length.
• Parallelograms have opposite sides that are parallel and equal in length.
• Rhombuses are parallelograms with all sides of equal length.
• Trapezoids have one pair of parallel sides.

Understanding the properties of these quadrilaterals can help in identifying and classifying them based on their attributes.

Remember to practice identifying and drawing different types of quadrilaterals to reinforce your understanding of their properties.
