There is no specific limitation on any one angle of an inscribed quadrilateral.


How can you find a missing side or angle of a right triangle?

180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.


How do you find the missing angle in a parallelogram?

When you add all four sides of a quadrilateral(all parallelograms are quadrilateral), It must equal 360 degrees. So what you do is you add up the three angles that are given, them subtract that sum from 360.


How do you find the size of the angle in a quadrilateral?

Use a protractor.

What is the first step when trying to find a missing angle?

If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.


How do you find the missing angle measures of a regular trapezoid if one angle measures 50 degrees?

There is no such thing as a regular trapezoid. REGULAR implies that all sides and all angles are equal. If that is the case, with a quadrilateral each angle would be 90 degrees, none would be 50.
