Advise from former students:
“Take notes and actually use them to help on other things”
Objective:1. Understand and use the basic
defined and undefined terms of Geometry.
2. Sketch relationships in Geometry.
Vocabulary: Undefined term, point, line, plane,
collinear, coplanar,
1.1 Points, Lines, and Planes
1.1 Points, Lines, and PlanesMake a chart in your notes that takes up about a whole page.
It should have seven rows.
The boxes should be big enough to write a sentence or draw a picture in.
Point- a location
1.1 Points, Lines, and PlanesFirst row:

Facts
has neither shape nor size
there is exactly one line through any two points
there is exactly one plane through any three points
Vocab
Known as an undefined term.
Points of the same line: collinear
Points on the same plane: coplanar
Naming Collinear and Coplanar Points:• Name three points that are collinear.
– L, N, O or M, N, P
• Name a point that are not coplanar.– P
• Name a line not contained by plane LMO.– Line MN, NP or MP
