A trapezoid is a quadrilateral, a figure with four sides. The sum of the interior angle measures of any quadrilateral is 360 degrees.
2 because there are 360 degrees in a quarilateral and 180 degrees in a triangle.
The sum of all the interior angles is 360 degrees.
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 four angles inside any 4-sided figure always add up to 360 degrees.
