What is the sum of the interior angles of a trapezoid?

When doing POLYGON problems, always use WORDS and LOGIC in your answers. You do not need to rely on formulas for everything! Fill in the blanks in the following examples and you should learn a lot about polygons! I have already filled in a lot for you. read more

Therefore, because you can split the shape into 2 triangles, the sum of the interior angles of a trapezoid (and any quadrilateral) is 360 degrees. read more

Think of it as starting out as a rectangle. Each angle is 90 degrees and there are four angles. 4 x 90 degrees = 360 degrees. read more

The sum of all of the angles in a trapezoid is 360 degrees. The sum of interior angles for an n-sided polygon is equal to 180(n-2) which, in this case, is 180(4-2) = 360. read more
