The square is the most regular of all the quadrilaterals, with four equal sides and four equal angles. Since every side is parallel to its opposite, cutting a square to produce two trapezoids is easy: just slice arbitrarily from a point on one side to another point on the opposite side. Cutting to create two trapeziums, defined as quadrilaterals with no parallel sides, actually is a little more complicated.

1
Label the corners of the square A, B, C and D, in a clockwise order, so that A is adjacent to B and D, and opposite to C.
-
2
Choose an arbitrary point somewhere inside the square, and label it E.
-
-
3
Draw a straight line from point A to point E, and another from point C to point E. This will divide the square into two trapeziums.
-
4
Cut along the straight lines you have drawn from point A to point E, and from point C to point E.
