Angles

In mathematics, an angle is a geometric figure formed by two rays (or line segments) that share a common endpoint, known as the vertex of the angle

In mathematics, an angle is a geometric figure formed by two rays (or line segments) that share a common endpoint, known as the vertex of the angle. The rays are called the sides of the angle. Angle measurement is typically given in degrees (°) or radians (rad).

There are several important types of angles:

1. Acute Angle: An acute angle is an angle that measures less than 90 degrees.

2. Right Angle: A right angle is an angle that measures exactly 90 degrees. It forms a perfect L-shape, resembling the corner of a square or rectangle.

3. Obtuse Angle: An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

4. Straight Angle: A straight angle is an angle that measures exactly 180 degrees. It forms a straight line, resembling a straight edge.

5. Reflex Angle: A reflex angle is an angle that measures greater than 180 degrees but less than 360 degrees.

6. Complementary Angles: Two angles are said to be complementary if their sum is exactly 90 degrees. In other words, when two angles are complementary, they add up to form a right angle.

7. Supplementary Angles: Two angles are considered supplementary if their sum is exactly 180 degrees. In other words, when two angles are supplementary, they add up to form a straight angle.

8. Adjacent Angles: Adjacent angles are a pair of angles that share a common ray as one of their sides and a common vertex. They do not overlap or intersect with each other.

9. Vertical Angles: Vertical angles are a pair of non-adjacent angles formed by two intersecting lines. They have the same vertex and are equal in measure.

10. Exterior Angle: An exterior angle is the angle formed when one side of a polygon is extended. It is the angle between that extended side and the adjacent side of the polygon.

It is important to note that angles can be measured in radians as well, where a complete circle measures 2π radians. Radians are often used in trigonometry and calculus for more precise calculations and understanding of angles.
