In the world of geometry, quadrilaterals are fascinating shapes with their own unique set of properties. Let's explore the characteristics of some common quadrilaterals.

Parallelogram: A parallelogram is a quadrilateral with two pairs of parallel sides. Its opposite sides are equal in length, and opposite angles are congruent. Examples of parallelograms in everyday life are rectangles and squares.

Rectangle: A rectangle is a parallelogram with all angles measuring 90 degrees. Opposite sides are parallel and equal in length. A common example of a rectangle can be seen in a typical door frame.

Rhombus: A rhombus is a parallelogram with all sides of equal length. Opposite angles are congruent, but unlike a rectangle, the angles are generally not 90 degrees. A popular example of a rhombus is the shape of a baseball diamond.

Square: A square is a special type of rectangle and rhombus, with all sides equal in length and all angles measuring 90 degrees. It possesses all the properties of both shapes. One can find squares in various everyday objects, such as tiles or computer screens.

These are just a few examples of quadrilaterals. They all have their own distinct properties and relationship with other geometric figures. By studying quadrilaterals, you'll gain a deeper understanding of the connections between shapes and their properties.

So embrace the mysteries of quadrilaterals, and let's dive into the world of geometry with enthusiasm!
