An angle that measured 145 degrees would be considered an "obtuse" angle because its measurement exceeds 90 degrees. Anything below 90 degrees would be considered an "acute" angle.
If it measures 90 degrees, then it is called a right angle.
A 90o angle is called a right angle.
An angle that measures to precisely 90o is called a right angle.
An angle that measures 180 degrees is a straight angle, or straight line.Line.
A right angle
an obtuse angle
an acute angle
a "right angle"
This type of angle is called a 'revoulotion angle'.
The supplementary angle to a 145 degree angle will be a 35 degree angle because 145 + 35 = 180.
