The angles are 157.5 degrees and 22.5 degrees
An angle whose measure is exactly 180 degrees is a straight angle.
Right Angle
Acute Angle: An angle whose measure is less than 90 degrees and greater then zero degrees is called an acute angle. Right Angle: An angle whose measure is 90 degrees is called right angle. Obtuse Angle: An angle whose measure is greater than 90 degrees and less than 180 degrees is called obtuse angle. Straight Angle: An angle whose measure is 180 degrees called a straight angle. Reflex Angle: An angle whose measure is greater than 180 degrees and less than 360 degrees is called a reflex angle. Complete Angle: An angle whose measure is 360 degrees is called a complete angle. Zero Angle: If the measure of an angle is zero it is called a zero angle.
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.
179 degrees
It is any angle whose measure is in the range (90, 18) degrees.
straight angle or line.
Acute angle
The measure of an angle whose sides overlap is 0 degrees. It is than not an angle, but rather a line.
An angle whose measure greater than 90 but less than 180 is an obtuse angle.
It is any angle whose measure is in the range (90, 18) degrees.
