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.

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 four angles inside any 4-sided figure always add up to 360 degrees.

The sum of the interior angles of a polygon with n sides is (n-2)*180 degrees.A trapezoid is a quadrilateral - it has 4 sides. Therefore its interior angles sum to (4 - 2)*180 = 360 degrees.

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.
