6. Translating geography vocabulary
6.1. Line Segment: a line that has two endpoints which means it stops.
6.1.1. Line segment GH OR Line segment HG (you need to use the endpoints )
6.2. Line: A line with arrows on both sides mean it continues forever in both directions.
6.2.1. Line GK OR Line HG (many options pick any two points on the line
6.3. Ray: One endpoint and one arrow. It stops at one end and continues forever in other directions.
6.3.1. Ray GH Or Ray GK (It must start with the endpoint.)
6.4. Angle: Two rays combined to create an angle.
6.4.1. Angle GKH Or Angke K (The Vertex must be in the middle

6.5.1. Circle H (Must be the center point)
7. Volume of a Rectangle
7.1. Formula to find volume of a rectangle= Length x width x height
8. Volume of a cylinder
8.1. Formula to find the volume of cylinder= Pi x radius x radius x right
