This topic mainly examines the analytical formula of undetermined coefficient method, the parallelism of straight lines, the similarity judgment and properties of triangles, and the area phase of triangles with the same base height. The transformation of equal area triangle is the key to this topic. This topic is quite difficult, but I believe you will understand it after reading the answer. This is the answer/exercise/math /7988 17. After mastering the key points of the topic, the topic is solved.

In the plane rectangular coordinate system, the coordinates of three vertices of triangle AOB are A (4 4,3), O (0 0,0) and B (6 6,0) respectively. Point M is the moving point on the edge of OB, the intersection point M is MN//AB, and point P is any point on the edge of AB, connecting AM, PM, PN and BN. Set point m. If you have a problem, you won't come again. Don't forget to adopt the helpful ones ~ Come on!
