愣是题目都没怎么理解,请各位帮我翻译一下,再分析一下,谢谢!!!
On the xy-coordinate plane, what is the area of a right triangle, one side of which is defined by the points(2,3) and (-4,0)?
1) the triagle's sides cross the y-axis at exactly two points altogether
2) the y-coordinate of the third vertex of the triangle is zero
谢谢各位,心里很着急!
在1中,三角形不可能一边穿过Y轴确认的两点啊,除非这条边就是Y轴啊, 不过我也觉得翻译起来就是这个意思
也看不懂这个题目的意思,只能帮顶一下,牛人快出来帮帮忙...
