Angles and Degree Measure with Confidence

Angles are geometric figures formed by two rays sharing a common endpoint. Degree measure quantifies the size of an angle within a circle, where a full circle is 360 degrees. Angles can be classified based on their measure: acute (less than 90 degrees), right (exactly 90 degrees), obtuse (more than 90 but less than 180 degrees), and straight (exactly 180 degrees). Understanding angle measure is fundamental in geometry and trigonometry, essential for various mathematical and scientific applications.
