动点型的三角形全等判定是三角形全等判定中的一个难点.许多同学因解题时没有适当地进行分类讨论而导致漏解.下面,通过例子向大家说明其解法.例1如图1,在平面直角坐标系中,已知点A(0,6),B(8,0).直线CD经过点0.动点P从A出发,沿A→O→B的路线运动,速度为每秒1个单位,到B点处停止; Moving point-based triangle congruent judgment is a difficult point in triangle congruent judgment.Many students fail to classify and discuss properly when they solve the problem, which will lead to the leaky solution. , The point A (0,6), B (8,0) is known in the Cartesian coordinate system. The straight line CD passes through point 0. The point P travels from A and travels along A → O → B at a velocity of 1 unit per second, stop at point B;
