Interior Angle Sum:

Visualization

Observe how the angles of a quadrilateral come together to form a full circle, illustrating why their sum is always 360°.

No matter how you reshape a quadrilateral, the total of its interior angles remains constant at 360 degrees.

Understanding Quadrilaterals

A quadrilateral is any polygon with four sides. Common examples include squares, rectangles, parallelograms, and trapezoids. Despite their varied shapes, a fundamental property unites them: the sum of their interior angles is always 360 degrees. This can be visualized by dividing any quadrilateral into two triangles. Since each triangle's angles sum to 180°, two triangles will naturally sum to 360°. This tool helps you appreciate this geometric principle, demonstrating a consistent rule in the world of shapes.
