Angles
An angle is the angle formed at the intersection of two or more rays. It is often represented by a letter, such as , with the apex pointing towards the direction of the rays.
Acute angles
An acute angle is an angle that measures less than 90 degrees. This means that the angle measures between 0 and 90 degrees.
Obtuse angles
An obtuse angle is an angle that measures between 90 and 180 degrees. This means that the angle measures between 90 and 180 degrees.
Reflex angles
A reflex angle is the angle formed when a ray of light reflects back on itself. This means that the angle is equal to the original angle
