Geometry Unit 1 - Logic and Angles
Day 1 - Chapter 1 Section 1: Understanding Points, Lines, and Planes
Objectives:
➢ I can recognize and use the markings used in geometry.
➢ I know the differences between Euclidean and Non-Euclidean Geometry
|Term |Definition |Picture |Notation |
|Plane |has two dimensions. It is represented by | | |
| |a shape that looks like a floor or wall, | | |
| |but it extends without end. | | |
|Point |has no dimension. It is represented by a | | |
| |dot. | | |
|Ray |AB consists of the endpoint A and all | | |
| |points on AB that lie on the same | | |
| |side of A as B. | | |
|Line |has one dimension. It is represented by a| | |
| |line with two arrowheads, but it extends | | |
| |without end. | | |
|Endpoint |is a point at the end of a segment or | | |
| |beginning of a ray. | | |
|Opposite Rays |have a common endpoint and form a line. | | |
|Collinear |are points that lie on the same line. | | |
|Coplanar |are points that lie in the same plane. | | |
|Noncollinear |Two or more geometric figures intersect | | |
| |if they have one or more points in | | |
| |common. The intersection of the figures | | |
| |is the set of points the figures have in | | |
| |common. | | |
|Noncoplanar |Two figures that are not in the same | | |
| |plane | | |

Vocabulary- Segment Addition & Bisectors
1) Segment- (line segment) part of a line consisting of two endpoints and all points between them
2) Distance- absolute value of the difference of the points (coordinates). It can also be called length. (Think of number line)
3) Congruence- same length or measure
4) Midpoint- point that bisects, or divides, the segment into two congruent segments.
5) Perpendicular Bisector- a line perpendicular to a segment at the segment’s midpoint.
Segment Addition
If B is between A and C, then AB + BC = AC.
Example:
If AB = 5, BC = 10, find AC.
