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

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
