An angle can range from 0 degrees to 360 degrees in a complete rotation. Angles can also be measured in radians, with a full circle equating to 2π radians. While theoretically, angles can be larger than 360 degrees when considering multiple rotations, for practical purposes in standard geometry, angles are typically confined to the 0-360 degree range.
A big angle.
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
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

you cant have a big right angle in a square because a right angle is 90 degree's and only 90 degree's
Each angle is 180/5 = 36 degrees
