Find the degrees.
Hey all,

Got a question here that states:

ABCD is a quadrilateral inscribed in a circle; AB and CD are each equal to the radius. AC and BD meet in E. Find the number of degrees in angle AEB.

I think I have the picture correct, as shown below:

Any help would be greatly appreciated. Thanks guys.

There is not enough information to solve this problem. Any other rectangle so drawn, even a square, would have and angle indicated as it is here. If it was a square, that might be sufficient additional information and the angle at the center would be 90. Otherwise it can't be found form this diagram.

then AB=AE=BE
then triangle ABE is equil triangle!
So, angle AEB is (you should know, right?)

(Or, am I reading the question incorrectly?)
