No. There are 5 types of angles:
Acute, Obtuse, Straight, Reflex, and Round (or perigon).
Acute is any angle below 90 degrees.
Obtuse is any angle above 90, but below 180.
Straight is any angle that reaches 180 degrees exactly (a straight line).
Reflex is any angle above 180 degrees, but below 360 degrees.
Round (perigon) is an angle where, from the starting points comes arount to a full revolution.
So, a 61 degree angle is below 90 degrees, therefore it is acute.

Why is a obtuse angle called a obtuse 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.
Is 120 degrees an acute or right or obtuse angle?
Obtuse. An acute angle is less than 90 degrees, a right angle is 90 degrees, and an obtuse angle is more than 90 degrees.
What angle is 110 degree?
110 degrees creates an obtuse angle.
Is an 125 degrees angle obtuse?
Any angle between 90 and 180 degrees - including 125 degrees - is an obtuse angle.
What is an angle called at 132 degrees?
It's an obtuse angle. Not exactly, an obtuse angle is an angle that is more than 90 degrees.
