Geometry terms notes worksheet featuring definitions and visual examples of key geometric concepts.

Let's solve this step by step. The task is to fill in the "DEFINITION" column for each geometry term based on the "WORD" and the visual "PICTURE" provided.

Here’s a completed version of the table with accurate definitions for each term:

✔ GEOMETRY TERMS NOTES

| WORD | DEFINITION | PICTURE |
|----------------|------------------------------------------------------------------------------|---------|
| Point | A location in space that has no size or dimension. It is represented by a dot. | ● |
| Line | A straight path that extends infinitely in both directions. It has no endpoints. | ↔ |
| Plane | A flat, two-dimensional surface that extends infinitely in all directions. | ←→↕ (rectangle with arrows) |
| Line Segment | A part of a line that has two endpoints and includes all points between them. | ●——● |
| Ray | A part of a line that has one endpoint and extends infinitely in one direction. | ●——→ |
| Angle | Formed by two rays that share a common endpoint (called the vertex). | ∠ |
| Parallel Lines | Two lines in the same plane that never intersect and are always the same distance apart. | ↔↔ (two lines with arrows) |
| Perpendicular Lines | Two lines that intersect at a right angle (90°). | ⊥ (with a square symbol indicating 90°) |

🔍 Explanation of Each Term:

1. Point:
- It represents an exact location in space.
- Has no length, width, or height.
- Usually labeled with a capital letter (e.g., point A).

2. Line:
- Extends infinitely in both directions.
- Represented with arrows on both ends.
- Named using any two points on it (e.g., line AB), or a lowercase script letter (e.g., line ℓ).

3. Plane:
- A flat surface that goes on forever in all directions.
- Contains many lines and points.
- Can be named with a single capital letter (e.g., Plane P) or by three non-collinear points.

4. Line Segment:
- A portion of a line with two distinct endpoints.
- Measurable because it has a finite length.
- Named by its endpoints (e.g., segment AB).

5. Ray:
- Starts at a point (endpoint) and goes on infinitely in one direction.
- Named starting with the endpoint and then another point on the ray (e.g., ray AB, where A is the endpoint).

6. Angle:
- Formed when two rays meet at a common endpoint (vertex).
- Measured in degrees (°).
- Named by the vertex or three points (e.g., ∠ABC, where B is the vertex).

7. Parallel Lines:
- Lines that lie in the same plane and never cross each other.
- Always the same distance apart.
- Symbol: \( \parallel \) (e.g., \( AB \parallel CD \)).

8. Perpendicular Lines:
- Lines that intersect at a 90° angle.
- Form four right angles at the intersection.
- Symbol: \( \perp \) (e.g., \( AB \perp CD \)).
