Consider the trapezium (or trapezoid) ABCD such that AD is parallel to BC.

Then angles DAB and ABC are consecutive interior angles (or co-interior angles) and sum to 180 deg.

Similarly, angles ADC and DCB sum to 180 deg.

Therefore, the sum of all four is 180 + 180 = 360 deg.

The sum of the angles of a trapazoid?

___________ /___________/ Not a very accurate diagram, but you might get the picture. There are 360 degrees in a trapezoid, same as for a rhombus, square and rectangle, or any 4-sided shape (withstraight edges)360 degrees, the same as for any quadrilateral.


What is the measure of the forth angle of a quadrilateral if one angle measures 106 degrees and the other measures 47degrees and the third one measures 133?

The sum of the interior angles of a quadrilateral must equal 360 degrees. If you know three of the angles, just subtract them from 360 to find the fourth angle. In this case: 360 - 106 - 47 - 133 = 74
