In the rectangular coordinate system above, if ΔOPQ and ΔQRS have equal area, what are the coordinates of point R ?

(1) The coordinates of point P are (0,12).

(2) OP = OQ and QS = RS.

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

EACH statement ALONE is sufficient.

Statements (1) and (2) TOGETHER are NOT sufficient.

##### 考题讲解

ΔOPQ和ΔQRS有相同的面积，OP*OQ/2 = QS*RS/2，即OP*OQ = QS*RS，想要求得R的坐标，则需要求RS长和OS长。

（1）  根据条件1，OP=12，所以有12*OQ = RS*QS。仅条件1无法求得RS和OS长。

（2）  根据条件2，OP=OQ，QS=RS，仅条件2也无法求得RS和OS长。
