A quadrilateral ABCD is drawn to circumscribe a circle. Prove that A B+C D=A D+B C

A quadrilateral ABCD is drawn to circumscribe a circle. Prove that A B+C D=A D+B C

A quadrilateral ABCD is drawn to circumscribe a circle. Prove that A B+C D=A D+B C

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.

In Fig.2, a quadrilateral ABCD is drawn to circumscribe a circle, with centre O, in such a way that the sides AB, BC, CD and DA touch the circle at the points P, Q, R and S respectively. Prove that AB + CD = BC + DA.

In a hexagon ABCDEF circumscribe a circle, prove that AB+CD+EF=BC+DE+FA.

If a hexagon ABCDEF circumscribe a circle, prove that AB + CD + EF=BC+DE+FA

If a hexagon ABCDEF circumscribe a circle, prove that AB + CD + EF=BC+DE+FA

In a quadrilateral ABCD, AB = CD and angle B = angle C . Prove that AC = AB

If the sides of a quadrilateral ABCD touch a circle prove that AB+CD=BC+AD.
