In the plane rectangular coordinate system, a (1,3), B (2,1), OA ‖ BC, OC ‖ AB, try to use the knowledge of translation to find the coordinate of point C

In the plane rectangular coordinate system, a (1,3), B (2,1), OA ‖ BC, OC ‖ AB, try to use the knowledge of translation to find the coordinate of point C

The origin o (0,0) can be obtained by translating a point one unit to the left and three units to the down, while the origin o (0,0) can be obtained by translating OA ∥ BC, OC ∥ AB, ∥ OC by translating AB one unit to the left and three units to the down, and the origin C (1, - 2) can be obtained by translating B (2,1) one unit to the left and three units to the down
