Answer: Below!

Step-by-step explanation:

Sure, here are three facts about quadrilaterals:

1. **Definition**: A quadrilateral is a polygon with four sides and four vertices (corners). The sum of the interior angles of any quadrilateral is always 360 degrees.

2. **Types**: Quadrilaterals can be classified into various types based on their properties, such as parallelograms, rectangles, squares, rhombuses, trapezoids, and kites. Each type has specific characteristics regarding side lengths, angles, and symmetry.

3. **Diagonals**: A quadrilateral has two diagonals, which are line segments connecting opposite vertices. The lengths of the diagonals and their relationships with the side lengths and angles of the quadrilateral can vary depending on the type of quadrilateral. For example, in a rectangle, the diagonals are congruent, while in a parallelogram, the diagonals bisect each other.
