Interior angles = 360 degrees
Exterior angles = 360 degrees
yes, it is possible for quadrilaterals to have four different angle measures.
The internal angles of a quadrilateral add up to 360 degrees.
108o
x is the angle you're looking for and 3x is the angle that when added to x must total 180 degrees. Therefore the angle is 45degrees (x + 3x = 180)
180- total of the first two angles= 3rd angle
Total 1440o; if regular, each angle = 144o
Each interior angle is 120o making the total 720o.

Quadrilateral
180 degrees.
120 degrees = 2X60....supplemental total = 180
To find the total degrees of a polygon take the number of sides n:(n-2) * 180which means that the total degrees is 540 and the measure of each angle is 108
