I need to prove that every line is contained by at least two planes using only the incidence axioms. This is what I have so far...(adsbygoogle = window.adsbygoogle || []).push({});

Conclusions Justifications

1. Let l be any line. Given

2. l has at least two points A and B such that I-5(4)

l = AB.

3. Space has at least 3 non-collinear points, I-5(2)

that is A,B,C

4. There exists line AC and line BC I-1
