👉 In mathematics, an angle is a figure formed by two rays that share a common endpoint, called the vertex of the angle. The measure of an angle is determined by counting the number of 90-degree segments (or "rotations") between the two rays that form the angle.
For example:
- A right angle measures exactly 90 degrees.
- An acute angle measures less than 90 degrees, while a straight angle measures exactly 180 degrees.
- An obtuse
