I WONDER - How Do I Calculate The Angles In A Quadrilateral?

The video tutorial explains that the sum of angles in a quadrilateral is 360 degrees. It covers the specific case of rectangles and squares, where each angle is 90 degrees. The tutorial also demonstrates how to find the fourth angle if three angles are known, and discusses the property of some quadrilaterals where opposite angles are equal.
