    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.

    If AB=CD=radius
    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?)

    Sorry! I must have been falling asleep. I had not read the question fully. Yes, you are correct.

    This isn't a perfect drawing but I would take the question as this. I'm just not sure where to go from there.
