acute
That angle was called 'revolution'.
Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.
It is an angle whose measure is between 90 and 180 degrees.
An acute angle is an angle whose measure is between 0 and 90 degrees.
An angle whose degree measure is between 0 and 90 is an acute angle. An angle whose degree measure is between 90 and 180 is an obtuse angle. These are basic properties of geometry.
An obtuse angle
acute
It is an angle whose measure is 144 degrees!
An angle whose measure is two times 90 degrees is a 180 degree angle, which is also a straight angle.
It is an angle whose measure is 83/180th of a turn,
It is an angle whose measure is 1/180th of a turn,
That angle was called 'revolution'.
90 degrees
It is an angle whose measure is 1/180th of a turn,
Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.
It is an angle whose measure is between 90 and 180 degrees.
