Study Notes
Undefined Terms in Geometry
- Three foundational concepts: point, line, and plane.
- A point is represented visually as a dot, indicating a precise location with no size.
- A line is a continuous set of points extending infinitely in two opposite directions, characterized by its straightness.
- A plane is defined as a flat two-dimensional surface extending infinitely in all directions.
Types of Lines
- Intersecting lines meet at exactly one point; this point is their intersection.
- Parallel lines are distinct in that they remain equidistant and do not meet, regardless of how far they are extended.
- Perpendicular lines are a specific case of intersecting lines that create a right angle (90 degrees) at their intersection.
Angles and Rays
- An angle is formed by two rays, which share a common starting point known as the vertex of the angle.
- The measure of an angle is determined by the amount of rotation from one ray to the other.
Geometric Solids
- A cone is categorized as a three-dimensional geometric solid.
- It consists of a single point called the vertex, connecting to a circular base that expands outward.
