Point

-most basic building block of geometry

-has no size

Point

Represented with a dot and a capital letter

Line

-Straight, continuous arrangement of infinitely many points

-Extends forever in two directions

Plane

-flat surface that extends infinitely along its length and width

Point, Line and Plane

- 3 building blocks of geometry

Collinear

-On the same line

Coplanar

-On the same plane

Line Segment

-Consists of two points called endpoints and all of the points between them that are collinear with the two endpoints

Congruent Segments

Two segments that have the same measure or length

Midpoint

- The point on the segment that is the same distance from both endpoints
