En [[Geometría]], un '''cuadrilátero tangencial''' es un [[Cuadrilátero]] [[Polígono convexo|convexo]] cuyos lados son todos tangentes a una [[Circunferencia]] inscrita en el cuadrilátero. Esta circunferencia se denomina [[Circunferencia inscrita|inscrita]].
== Características ==
En un cuadrilátero tangencial, cada par de lados opuestos suman la misma longitud, que es la mitad del perímetro del cuadrilátero:
: <math> a + c = b + d = \frac{a + b + c + d}{2} </math>
