| Abstract: | In general analitic geometry textbooks, the solvability on the problem to find a straight
line through passing a definite point and two definite straight lines is often isnored. To counter this
situation, this artical presents the sufficient and necessary conditions on the problem that can be
solved. And gives some examples to show what mistakes will be created if ignore the solvability. |
