A right angle is a angle with 90o
Well, honey, if you're talking about an angle that measures 170 degrees, you're looking at an obtuse angle. It's bigger than a right angle but smaller than a straight angle. So, grab your protractor and get measuring!
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
An angle of 98 degrees is an obtuse angle
