The Big 3 of Geometry Point Line Plane

Point Definition: Location only; it has no size. How to Name: One capital letter. Example: P Picture:

Line Definition: Straight continuous arrangement of infinitely many points. How to Name: Two capital letters with a line with 2 arrows above it. Example: 𝐶𝐷 Picture:

Plane Definition: Flat surface that extends infinitely along its length and width. How to Name: One capital script (cursive) letter. Example: M Picture:

Collinear Definition: On the same line Picture:

Coplanar Definition: On the same plane Picture:

Ray Definition: A point on a line, and all the points that lie on one side of this point. How to Name: Two capital letters and a line with one arrow above. The endpoint must be the first letter. Example: 𝐹𝑅 Picture:

Line Segment Definition: Part of line. Does not extend indefinitely. How to Name: Two capital letters and a line on top. Example: 𝐴𝐵 Picture:

Midpoint Definition: Point on a line segment that is the same distance from both end points. How to Name: One capital letter Example: C Picture:

Congruent Definition: Equal. The same length. The same size. The same measure. Picture: Drawn with “hash” marks.

Bisects Definition- Divides into two equal, congruent parts. Picture: Line: divides into two congruent segments Angle: divides into two congruent angles Picture:
