LINE : When a line segment is extended indefinitely in both directions it forms a line.
A line has no end points.
A line has no definite length.
A line cannot be drawn, it can simply represented on the plane of a paper.
To draw a line would mean to represent it. sometimes, we label lines by small letters l, m, n, etc.
ANGLE : When two straight lines meet at a point they form an angle.
An angle is measured in degrees, minutes and seconds.

Line and Angle
Line:
A line is a straight path that goes on forever in both directions. It is made up of an infinite number of points. A line can be represented by a straight line with arrows at both ends to indicate that it extends indefinitely.
Examples of Lines:
- Horizontal line: A line that runs parallel to the horizon.
- Vertical line: A line that runs perpendicular to the horizon.
- Diagonal line: A line that is neither horizontal nor vertical.
Angle:
An angle is formed when two lines or rays meet at a common endpoint called a vertex. Angles are measured in degrees and are classified based on their measure as acute (less than 90 degrees), right (exactly 90 degrees), obtuse (more than 90 degrees but less than 180 degrees), and straight (exactly 180 degrees).
Examples of Angles:
- Right angle: An angle that measures exactly 90 degrees.
- Acute angle: An angle that measures less than 90 degrees.
- Obtuse angle: An angle that measures more than 90 degrees but less than 180 degrees.
Lines and Angles:
In geometry, lines and angles are fundamental concepts that are used to define shapes and figures. Lines can intersect to form angles of different measures, which are essential in solving geometric problems and understanding the properties of various shapes. Understanding the relationship between lines and angles is crucial in geometry and helps in solving problems related to angles formed by intersecting lines, parallel lines, and perpendicular lines.
