commonly called a right angle
Angle b is acute angle, if any angle less than 90 degrees then it is called acute angle if more than 90 degrees then it is obtuse angle if it is equal to 90 degrees then it is right angled
A Right Angle is 90 degrees.
A Right Angle.
NO. An obtuse angle is over 90 degrees, but under 180 degrees. Acute angle is under 90 degrees.
An angle of 90 degrees is a right angle.
An angle which measure exactly 90 degrees is called a right angle.
An angle which measures 90 degrees is called a right angle. An angle of less than 90 degrees is an acute angle and one which is more than 90 degrees is an obtuse 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.
It is called an obtuse 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.
It is called a "right angle".
A right angle = 90 degrees
When an angle has a measure of 120 degrees, it is an obtuse angle. When an angle is an obtuse angle its measure is between 90 and 180 degrees. That is: 90 degrees < obtuse angle < 180 degrees.
Less than 90 degrees is an acute angle, a 90 degree angle is a right angle, and an angle greater than 90 degrees is called an obtuse angle.

That's an "acute" angle.
