下面是 2 0 0 3年河北省一道中考数学探究性试题 .探究规律 :图 1如图 1,已知直线m∥n ,A、B为直线n上两点 ,C、P为直线m上两点 .( 1)请写出图 1中面积相等的各对三角形 ;( 2 )如果A、B、C为三个定点 ,点P在m上移动 ,那么 ,无论点P移动到任何位置 ,总有与△ABC的面积相等 .理由 The following is a 300-year mathematics inquiry question in Hebei Province. Explore the law: Figure 1 As shown in Figure 1, the known line m∥n, A, B are two points on the straight line, C, P are two lines on the m Points. (1) Please write out the triangles of equal area in Figure 1. (2) If A, B, and C are three fixed points, and point P moves on m, then, regardless of the point P moves to any position, There is an equal area with △ABC. Reasons
