In geometry, an angle is formed by two rays that share a common endpoint, called the vertex. Angles are typically measured in degrees. Classifying angles involves identifying them based on their degree measures. The main types of angles we'll explore are acute angles (less than 90°), right angles (exactly 90°), obtuse angles (greater than 90° but less than 180°), and straight angles (exactly 180°). Understanding these classifications is crucial for further studies in geometry and trigonometry.
Match the terms with their definitions:
| Term | Definition |
|---|---|
| 1. Acute Angle | A. An angle exactly 180° |
| 2. Right Angle | B. An angle greater than 90° but less than 180° |
| 3. Obtuse Angle | C. An angle less than 90° |
| 4. Straight Angle | D. An angle exactly 90° |
An _______ angle is smaller than a right angle. A _______ angle is exactly 90 degrees. An obtuse angle is _______ than a right angle but less than a _______ angle. A straight angle forms a _______ line.
