Study Notes

Types of Angles

Acute Angles
- Definition: An angle measuring less than 90 degrees.
- Characteristics:
  - Can be found in various geometric shapes (triangles, pentagons).
  - Examples include 30°, 45°, and 60° angles.
Obtuse Angles
- Definition: An angle measuring more than 90 degrees but less than 180 degrees.
- Characteristics:
  - Appears wider than a right angle.
  - Examples include 120° and 150° angles.
Reflex Angles
- Definition: An angle measuring more than 180 degrees but less than 360 degrees.
- Characteristics:
  - Appears larger than a straight angle but less than a full circle.
  - Examples include 210° and 300° angles.
Straight Angles
- Definition: An angle that measures exactly 180 degrees.
- Characteristics:
  - Forms a straight line.
  - Can be visualized as two rays pointing in opposite directions.

Types of Angles

Acute Angles
- Measure less than 90 degrees.
- Commonly found in triangles and other geometric shapes like pentagons.
- Examples: angles measuring 30°, 45°, and 60°.
Obtuse Angles
- Measure more than 90 degrees but less than 180 degrees.
- Wider appearance than a right angle.
- Examples: angles measuring 120° and 150°.
Reflex Angles
- Measure more than 180 degrees but less than 360 degrees.
- Larger than a straight angle but smaller than a full circle.
- Examples: angles measuring 210° and 300°.
Straight Angles
- Measure exactly 180 degrees.
- Geometrically represented as a straight line.
- Formed by two rays extending in opposite directions.
