Question: Help me with angles
1. Let's start by understanding what an angle is. An angle is formed by two rays (or line segments) that share a common endpoint called the vertex.
2. The measure of an angle is usually given in degrees ($^{\circ}$) or radians.
3. Common types of angles include:
- Acute angle: less than $90^{\circ}$
- Right angle: exactly $90^{\circ}$
- Obtuse angle: between $90^{\circ}$ and $180^{\circ}$
- Straight angle: exactly $180^{\circ}$
4. Important rules about angles:
- The sum of angles on a straight line is $180^{\circ}$.
- The sum of angles around a point is $360^{\circ}$.
- In a triangle, the sum of the interior angles is always $180^{\circ}$.
5. If you have a specific problem involving angles, please provide the details so I can help you solve it step-by-step.
