The answer depends on what information is available but there is no simple solution. Using a protractor seems the best bet.
i don't know it this helps, but the sum of the angles in a quadrangle is 360 !
The sum of the angles in a quadrangle is 360 degrees, whatever the side lengths.
you add the three other angles and subtract that from 360
make it a quadrangle & divide by 2.
On a protractor.
How do you find the area of an unequal quadrangle?
The sum of all four angles inside any 4-sided figure is always 360 degrees.
Using the formula: (number of sides -2)*180 = sum of interior angles
On a protractor and at each corner (vertex) of the polygon.
For any n-sided regular polygon the exterior angles are 360/n degrees.

Type your answer here... The sum of the angles in all polygons is 360 degrees. Thus, if you know the measure of the interior angles you can divide 360 by the measurement to find out how many interior angles and sides there are.
