Angle

two rays that meet at a single endpoint.

Right Angle

An angle that has a square corner.

A right angle is sometimes called a 90 degree angle.

Acute Angle

An angle that is less than a 90 degree angle.

An acute angle looks like a book that is more closed than open.

Obtuse Angle

An angle that is greater than a 90 degree angle.

An obtuse angle looks like like a book that is more open than closed.
