As with all things in geometry, wiser, older geometricians have trod this ground before you and have shown the way. The parallel postulate is very important in doing geometric proofs. In this worksheet, students complete two geometry proofs.

Parallel lines and supplementary angles.

To use geometric shorthand, we write the symbol for parallel lines as two tiny parallel lines, like this Proof by contradiction that corresponding angle equivalence implies parallel lines. In geometry, parallel lines are lines in a plane which do not meet; Therefore the triangle $bcd$ is similar to $pqf$, and since they have the edges at $f$ in common, the edges opposite $f$ have to be parallel.
