# how to make lines and angles working model project

### Lines

A line is a straight path that extends infinitely in both directions. It is one-dimensional and has no thickness.

Lines are fundamental elements in geometry and serve as the foundation for various geometric concepts.

### Types of Lines:

• Straight Line (or Line Segment): A straight path that extends infinitely in both directions. A line segment is a finite portion of a straight line.
• Ray: A part of a line that has one endpoint and extends infinitely in one direction.
• Parallel Lines: Lines that are always the same distance apart and will never intersect.
• Perpendicular Lines: Lines that intersect at a right angle (90 degrees).

## Angles:

An angle is formed by two rays or line segments that share a common endpoint. The common endpoint is called the vertex, and the rays are the sides of the angle.

### Types of Angles:

• Acute Angle: An angle measuring less than 90 degrees.
• Right Angle: An angle measuring exactly 90 degrees.
• Obtuse Angle: An angle measuring more than 90 degrees but less than 180 degrees.
• Straight Angle: An angle measuring exactly 180 degrees.
• Reflex Angle: An angle measuring more than 180 degrees but less than 360 degrees.
