A circle touches all the four sides of a quadrilateral ABCD.Prove that AB+CD=BC+DA

A circle touches all the four sides of a quadrilateral ABCD .Prove that: AB+CD=BC+DA

A quadrilateral ABCD is drawn to circumscribe a circle. Prove that AB+CD=AD+BC. or A circle touches all the four sides of a quadrilateral ABCD. Prove that AB+CD=BC+DA.

If a circle touches all the sides of the quadrilateral ABCD,then show that AB+CD=BC+DA.

A circle touches all the four sides of a quadrilateral ABCD with AB=6cm, BC=7cm and CD=4cm. Find AD.

A circle touches all sides of quadrilateral ABCD then which one of these is true :

In Figure 3, a circle touches all the four sides of a quadrilateral ABCD whose sides are AB = 6 cm, BC = 9 cm and CD = 8 cm. Find the length of side AD.

In Figure 3, a circle touches all the four sides of a quadrilateral ABCD whose sides are AB = 6cm,BC=9cm and CD=8cm. Find the length of side AD.

A circle touches all the four sides of a quadrilateral ABCD. If AB = 9 cm, BC= 8 cm and CD = 12 cm, then what is DA equal to?
