Geometry Basics
Vertices and edges
- The corners of a polygon are called vertices and the sides are called edges.
Plane
- A plane is a flat 2 dimensional surface like the surface of a table.
Parallel lines
- If two lines are parallel they point in exactly the same direction and will never meet.
- Parallel lines are indicated by drawing matching arrows on the lines.
- If there are two different pairs of parallel lines then different arrows are used for each pair.
Perpendicular lines
- Two lines are perpendicular if the angle between them is a right angle.
