1. Introduction to Geometry: Points, Lines, and Planes

2. Basic Geometric Figures
Point: Location in space represented by a dot and a capital letter.
Points have no size, only position.
Example:

3. Basic Geometric Figures
Line: Connected series of points that extends in both directions without end (represented by arrows).
Lines can be named by any two points on the line, or by one lowercase letter.

4. Basic Geometric Figures
Plane: Infinite set of points forming a flat surface extending in all directions, represented by a four-sided figure.
Example:

5. Basic Geometric Figures (Aspence)
SPACE—is 3-D
SPACE—the set of all points.

6. Basic Geometric Figures
Segment: Part of a line bounded by two endpoints.

7. Basic Geometric Figures
Ray: Part of a line that starts at a certain (end)point and continues forever in one direction.

8. Naming Geometric Figures
Intersection: The point shared by two crossing figures.

9. Real Life Example FedEx E Find four segments that intersect AC.
Find three segments || to AC.
Find four segments skew to AC. A F B
FedEx G C H D
