Angles

# Types of angles

Types of angles:

• A right angle is an angle whose measure is 90º. A right angle is often identified by a small square drawn inside it.
• An acute angle is an angle whose measure is larger than 0º but less than 90º.
• An obtuse angle is an angle whose measure is larger than 90º but less than 180º.
• A straight angle is an angle whose measure is 180º. Such an angle is, in fact, a straight line.
