What is a Tangential Quadrilateral?
In Euclidean geometry, a Tangential Quadrilateral (sometimes just tangent quadrilateral) or circumscribed quadrilateral is a convex quadrilateral whose sides all can be tangent to a single circle within the quadrilateral. This circle is called the incircle of the quadrilateral or its inscribed circle, its center is the incenter and its radius is called the inradius. Since these quadrilaterals can be drawn surrounding or circumscribing their incircles, they have also been called circumscribable quadrilaterals, circumscribing quadrilaterals, and circumscriptible quadrilaterals.
How to Calculate Inradius of Tangential Quadrilateral given Area?
Inradius of Tangential Quadrilateral given Area calculator uses Inradius of Tangential Quadrilateral = Area of Tangential Quadrilateral/(Side A of Tangential Quadrilateral+Side C of Tangential Quadrilateral) to calculate the Inradius of Tangential Quadrilateral, The Inradius of Tangential Quadrilateral given Area formula is defined as the length of the straight line from the center to the circumference of the inscribed circle of the Tangential Quadrilateral, calculated using its area. Inradius of Tangential Quadrilateral is denoted by ri symbol.
