If ABCD is a cyclic quadrilateral, then find which of the following statements is not correct.​

Answer»

ANSWER:

B

Step-by-step EXPLANATION:

In a CYCLIC QUADRILATERAL ABCD

A + C = 180

sin[A+C]=sin180=0

B + D = 180

cos[B+D]=cos180=-1

sin[A+B+C+D]=sin360=0

But it is not necessary that sin[A+B]=0
