Label the different parts of the coordinate grid.

A Quick Review of the Coordinate Grid Coordinates – ordered pair (x, y) – shows location of a point x – 1st coordinate (left and right) y – 2nd coordinate (up and down)

Chapter 1.1 Collinear – 3 or more points that Noncollinear – the points on the same line A B C D lie on the same line do not lie

Ch. 1.2 Points, Lines, and Planes Point – ***All Geometric Figures are made up of Points!! A - no dimension - represented by a dot - named by a Capital letter or an ordered pair

Ch if 2 points are labeled on the line, the line can be called line AB or BA A B k - the ends are extended infinitely - has no thickness or width - named by a lower case script letter Line – a segment connecting two points where:

Ch. 1.2 Plane – Flat surfaces such as a wall - no thickness - extends infinitely____________!! - modeled as: - named by a Capital script letter - or 3 noncollinear points in the plane Q P S R

Space – set of all points - contains all _______, _______, and _________. Coplanar – Not coplanar – A B C D T Name coplanar points… Name not coplanar points…
