Please Ask My Dear Aunt Sally

Dear Aunt Sally,

What is the name of an angle whose measure is between 180 and 360 degrees?

Signed,
Para Rays


Dear Para,

An angle whose measure is between 180 and 360 degrees is called a reflex angle. Please remember that an acute angle is not an angle whose measure is less than 90 degrees, but instead an acute angle is an angle whose measure is between 0 and 90 degrees. An obtuse angle is an angle whose measure is between 90 and 180 degrees.

Signed,
Your Dear Aunt Sally
