    In figure, ABC is an equilateral triangle. The coordinates of vertices B and C are (3, 0) and (- 3, 0), respectively. Find the coordinates of its vertex A.  

Answer:

     units     [      units ]                           units               (1/2)                 In equilateral triangle all sides are equal. units and                 Given, in                                           [using Pythagoras theorem]                                                  (1)                                                           units                           Coordinates of A are     (1/2)                  Point lies on y-axis, so its x-coordinate will      be zero.
