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.
Obtuse angle
commonly called a right angle
An obtuse angle
It is an angle whose measure is 98/360 = 49/180 of a whole circle.
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.
Acute angle
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.
Obtuse angle
An obtuse angle is DEFINED as an angle whose measure is greater than 90 degrees and less than 180 degrees.
It is any angle whose measure is in the range (90, 18) degrees.
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 measure is two times 90 degrees is a 180 degree angle, which is also a straight angle.
this is a acute angle
It is an angle whose measure is in the range (90, 180) degrees.
