This is a problem of combining numbers with shapes and moving points. First of all, we should memorize several concepts learned in textbooks, be good at using them, and do some basic questions in moderation to consolidate concepts. For example, there is a moving point C on line AB, remember that AC+BC=AC, etc. Although simple, sometimes you can't do it without seeing the problem, and sometimes you should pay attention. Remember to prove that the triangle segments and angles are equal.

In a triangle, ① the angles and sides of the same triangle are equal.

An isosceles triangle has two equal waists and three equal sides. ② The bisector of the top angle of an isosceles triangle, or the bisector of the height, center line and bottom edge. ③ An isosceles triangle with an angle of 60 is an isosceles triangle or an equilateral triangle.

A straight line passing through the midpoint of one side of a triangle and parallel to the other side will bisect the third side. It's important for you to sum up yourself and pay more attention to the influence.

Function must be solid, function is the key to mathematical problems!

Don't limit yourself to pictures, or you will limit your thinking and draw often.

Let me summarize these first. You can keep asking questions. The most important thing is to summarize yourself. Others always remember that they are not as good as themselves! I wish you study hard. +Happy New Year ~! , 10, the combination of linear function and triangle in eighth grade mathematics. Problem solving skills of moving points on triangles

Is the relationship between s and x of the moving point p on the triangle.
