Hello, aldrincabrera!

I assume you didn't try sketching . . .

Are the diagonals of a circumscribable quadrilateral always congruent?

Of course not!

Code:
                A
D    * o *    B
o           o
*               *
*                 *

*                   *
*                   *
*                   *

*                 *
*               *
*           *
* o *
C

$\text{Quadrilateral }ABCD\text{ is circumscribable,}$
. . $\text{but }AC \ne BD.$
