Parallel lines and a transversal
Parallel lines are always the same distance apart. A transversal cuts across them and makes eight angles.
| Angle pair | Rule | Shape |
|---|---|---|
| corresponding angles | equal | F-shape |
| alternate angles | equal | Z-shape |
| co-interior angles | add up to 180° | U/C-shape |
Kinds of lines
| Line | Meaning |
|---|---|
| Line segment | Has two end points: AB |
| Ray | Starts at one point and goes on forever in one direction |
| Straight line | Goes on forever in both directions |
| Parallel lines | Always stay the same distance apart and never meet |
| Perpendicular lines | Meet at 90° |
Remember this and test yourself
- Corresponding angles are equal (F).
- Alternate angles are equal (Z).
- Co-interior angles add up to 180° (U).
Write these points in your book. Read them again the night before the test.
F and Z are equal; U makes 180.
