**Investigate conditions for two lines to be parallel and solve simple numerical problems using reasoning (ACMMG164)**

**LO: To investigate conditions for two lines to be parallel.**

**Know:**

- That lines exist.
- That lines can be classified as parallel or non-parallel depending on their angles

**Understand:**

- That parallel lines have identical angles and are equally far apart..
- That non-parallel lines are not equally far apart.

**Do:**

- I can determine if two lines are parallel or non-parallel.

**Parallel and Non-Parallel Lines.**

**Parallel and Non-Parallel Lines.**

### Perpendicular lines intersect at 90 degrees and parallel lines never intersect no matter how far they are extended.
