How can you say that the grey triangle is isosceles?

Code:

          *           *
        *               *
       *                 *

      *         O         *
      *         ♥.        *
      *         *:*.      *
                *:::*.
       *        *:::::*. *
        *       *:::::::♥
          *     *:::: *  B
              * ♥ *
                A
