90 degrees
When the angle you are measuring is obviously an obtuse angle (angle above 90 degrees, or when you draw a box in the angle and it turns out bigger than it's supposed to) you use the big numbers. When the angle is obviously acute (opposite definition of obtuse), you use the little numbers.
A regular quadrilateral is a square and each angle is 90 degrees (i.e. a right angle).
Over 90 degrees
