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 big angle.
A reflex angle is one greater than 180o
90 degrees
they add up to 180 so it depends. you have to know one of the measures

A big angle.
If the angle is measured at 130 degrees then it is called an obtuse angle.
An acute Angle is smaller than a right angle, for example: If you have the Big hand on the 12 and the small hand on the 2 the inside angle is a acute angle
A reflex angle is one greater than 180o
180 degrees
90 degrees

In order for your to know the weight must know the thickness of the angle bar.
the only angle I know is exterior angle ; hope this helps ! xD
An angle below 90 degrees is know as an acute angle.
