An angle that has 170 degrees is considered an "obtuse" angle. This is because it exceeds 90 degrees. Anything below 90 would be an "acute" angle.

An obtuse angle.
Well, honey, the supplement of a 10 degree angle is 170 degrees. So if you add those two angles together, you'll get a nice, straight line of 180 degrees. Simple math, darling.
A reflex angle is one that is more than 180 degrees but less than 360 degrees. If the reflex angle measured 190 degrees, then there would be a 170 degree, or obtuse, angle opposite it. If the reflex angle measured 270 degrees, then there would be a 90 degree, or right, angle opposite it. If the reflex angle measured 300 degrees, then there would be a 60 degree, or acute, angle opposite it. It helps to draw or picture these angles as sectors of a circle.
The complement of a 55 degree angle is a 35 degree angle
