It is an obtuse angle
The first answer is wrong. An acute angle is an angle less then 90 degrees. A 164 degree angle would be obtuse, which is an angle higher than 90 degrees.
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.
There can be 10 obtuse angles. If there are no reflex angles there can by up to three acute angles (I think).
They can be acute, obtuse or right - or even reflex. The only condition is that their sum is 900 degrees.
Zero to 90 = acute 90 = right 90 to 180 = obtuse 180 = straight
Acute , to start with, then right, obtuse, straight and reflex.
obtuse + acute = obtuse or straight or reflex.
Acute or obtuse: Yes. Straight: No.

They can make an obtuse angle, a straight angle or a reflex angle.
The angles are, acute, obtuse, right, straight, and reflex.
Acute, right, obtuse, straight, reflex.
It can have angles which are acute, right, obtuse or reflex. Not straight angles, though.
intersecting, parallel, acute, right ,obtuse, straight, perpendicular, reflex
acute angle obtuse angle right angle reflex angle a straight angle
They are: acute, right angled, obtuse, reflex, straight, and i think thats about it
