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
An angle of 90 degrees is called a right angle.
A right angle triangle
A right angle.
A obtuse angle is called an obtuse angle because if obtuse means bigger in degrees and a right angle is 90 degrees than a obtuse angle must be over 90 degrees.
If an angle is equal to 90, then it can't be more than 360.An angle that is equal to 90 degrees is called a "right angle".
