Angles are one of the basic building blocks of geometry. They are formed when two rays (straight lines that extend infinitely in one direction) meet at a common point, called the vertex. The size of an angle is measured by the amount of rotation between the two rays, usually in degrees or radians.
Angles can be classified into different types based on their measure.
➡Acute angles: Less than 90 degrees (think of a sharp corner).
➡Right angles: Exactly 90 degrees (like the corner of a square).
➡Obtuse angles: More than 90 degrees but less than 180 degrees (wider than a right angle but not a straight line).
➡Straight angles: Exactly 180 degrees (like a straight line).
➡Reflex angles: More than 180 degrees but less than 360 degrees (they turn more than halfway around but not all the way around).
➡Full angles: Exactly 360 degrees (a complete circle).
