Line Point Plane

Points, Lines, & Planes

First, let's start with a review from last class!

Point

• A point is location with no size or dimension.

• ​To name a point use a CAPITAL LETTER!

Line

• A line is made up of 2 or more points.

• ​It has no thickness or end.

• ​To name a line use either the lower case letter or two points on the line with the proper notation!

Plane

• A plane is a flat surface made up of points.

• A plane extends indefinitely in all directions

• ​To name a plane use the script uppercase letter or three NON-COLLINEAR points.

Some Other Important Facts

​

Collinear Points - Points that are on the same line!

​

​Coplanar Points - Points that are on the same plane!

​

​Two lines (if not parallel) intersect a point.

​

​Two planes (if not parallel) intersect at a line.

Awesome, you have completed the Quizizz!

​Now go to the Practice Worksheets Tab of OneNote and complete the Points, Lines, Planes Practice Worksheet. The sub also has paper copies for anyone who would like one!

​

I will check that this worksheet is completed next class!
