they should be all 180degrees if i understand what you are saying
Straight angle
A right angle is defined as 90 degrees, or pi/2 radians.
reflex
Obtuse.
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 with measure equal to 90 is called a right angle.
50% of what degree. 50% of 360degrees is 180degrees 50% of 180degrees is 90degrees 50% of 90degrees is 45degrees 50% of 260degrees is 130degrees
an obtuse angle
The instrument used to measure a angle is called a protractor!
That angle was called 'revolution'.
An angle of 90 degrees is called a right angle.
