Study Notes
- Geometry is the study of lines, shapes, angles, distances, and spatial elements like points, lines, and planes.
- Points are tiny dots in space used to describe specific locations; naming them is important for clarity.
- Lines are formed by connecting points; a line segment has a beginning and end, while a line extends infinitely in both directions.
- A ray is a line with a beginning point but no end point, extending infinitely in one direction.
- Points are named with letters; lines are named using the points they pass through; rays have a beginning point and extend in one direction.
- A plane is a two-dimensional object like a flat surface where points can lie; a line is one-dimensional, and a plane is two-dimensional.
- In a three-dimensional space, points can exist in different planes, requiring movement in the third dimension to reach them.
- Three points are needed to define a plane; connecting them forms a triangle, which serves as a flat surface within the plane.
