在中考试题中，常有求直线与坐标轴围成的三角形面积的试题出现．根据三角形的面积公式高，需要根据直线与坐标轴围成的不同的三角形确定三角形的底和高．对于这类问题，可分为下面三种情况，现举例说明如下．一、一条直线与而坐标轴围成的直角三角形，两条直角边的长分别是这 In the mid-test questions, there are often questions about the area of ​​the triangle that is drawn from the straight line and the coordinate axis. According to the formula of the area of ​​the triangle is high, the bottom and height of the triangle need to be determined according to the different triangles enclosed by the straight line and the coordinate axis. For this kind of problem, it can be divided into the following three cases, examples are as follows. A right-angled triangle surrounded by a straight line and a coordinate axis. The lengths of the two right-angled sides are respectively
