    please help

    Hi,

    May someone help me please? I have been at the problem for a long time now.


    Isosceles triangle XYZ is placed on a coordinate plane to be used for a coordinate proof. What could be the coordinates of its vertices?

    Thank you for the help.

    Hello, JayJay!

    Are you sure you know what an isosceles triangle is?

    What could be the coordinates of its vertices?

    Here's one way . . .
    Code:
                    |
                    *(0,b)
                   *|*
                  * | *
                 *  |  *
                *   |   *
               *    |    *
              *     |     *
             *      |      *
        - - * - - - + - - - * - -
         (-a,0)     |     (a,0)

    Here's another . . .
    Code:
            |        
            |       *(Ża,b)
            |      *:*
            |     * : *
            |    *  :  *
            |   *   :   *
            |  *    :    *
            | *     :     *
            |*      :      *
        - - * - - - + - - - * - -
          (0,0)           (a,0)
