A tangential quadrilateral, also known as an inscribed quadrilateral or cyclic quadrilateral, is a four-sided polygon whose vertices lie on the circumference of a circle. This means that all four sides of the quadrilateral are tangent to a single circle.

Key characteristics of tangential quadrilaterals include:

- Each vertex of the quadrilateral touches the circumference of the circle.
- The sum of opposite angles in the quadrilateral is always supplementary, meaning they add up to 180 degrees.
- The diagonals of the quadrilateral intersect at a point known as the circumcenter, which is the center of the circle circumscribed around the quadrilateral.
- Tangential quadrilaterals exhibit various interesting properties and relationships between their angles, side lengths, and the radius of the circumcircle.

Tangential quadrilaterals play a significant role in geometry due to their unique properties and relationships. They are extensively studied in both pure mathematics and applied fields, such as engineering, architecture, and computer graphics.

Understanding tangential quadrilaterals helps mathematicians and practitioners analyze and solve problems related to polygonal geometry, circle geometry, and trigonometry. They are also relevant in the study of geometric constructions, where tangential quadrilaterals often serve as building blocks for constructing more complex figures.

Tangential quadrilaterals possess several noteworthy properties and attributes that distinguish them from other types of quadrilaterals:

- Each vertex of the quadrilateral touches the circumference of the circle inscribed within it.
- Opposite angles in the quadrilateral are supplementary, meaning they add up to 180 degrees.
- The sum of the lengths of opposite sides of the quadrilateral is equal.
- The diagonals of the quadrilateral intersect at a point known as the circumcenter, which is the center of the circle inscribed within the quadrilateral.
- Tangential quadrilaterals satisfy various angle and side relationships, including the properties of cyclic quadrilaterals.

There are several types of tangential quadrilaterals, each with its own distinct properties and characteristics:

- Rectangles and squares: These are tangential quadrilaterals with all right angles.
- Rhombi: Tangential quadrilaterals with all sides of equal length.
- Parallelograms: Quadrilaterals with opposite sides that are parallel and equal in length.
- Trapezoids: Quadrilaterals with one pair of parallel sides.
- Kites: Quadrilaterals with two distinct pairs of adjacent sides that are equal in length.
