Key Concepts and Definitions:
- Point: A location in space with no dimensions.
- Line: A straight path that extends infinitely in both directions with no endpoints.
- Line Segment: A part of a line with two endpoints.
- Ray: A part of a line that starts at a point and extends infinitely in one direction.
- Plane: A flat, two-dimensional surface that extends infinitely in all directions.
- Angle: Formed by two rays with a common endpoint called the vertex.
- Types of Angles:
- Acute Angle: Less than 90 degrees.
- Right Angle: Exactly 90 degrees.
- Obtuse Angle: More than 90 degrees but less than 180 degrees.
- Straight Angle: Exactly 180 degrees.
