The answer depends on whether or not the hexagon is regular, partly regular or totally irregular. In the last case it will not help.
It also depends on whether you start off with a regular hexagon standing with one vertex above another or standing on one of its sides!
How can a you make a hexagon using a trapozid and 2 triangles
What are two ways to make a trapezoid
A big triangle if you put the triangle on the trapezoid's short parallel side, or a parallelogram if you put it on one of the trapezoid's ends. In both cases the triangle must be exactly the right shape and size or you will only have an irregular quadrilateral, pentagon, or hexagon. (Placing an appropriately-sized triangle on the long parallel side will also yield a pentagon - likely irregular.) Additionally, if a vertex of the triangle touches the trapezoid it can also make an irregular concave heptagon!
Look at it the other way. Draw a hexagon, and draw two horizontal lines, in each case from one vertex to another one. That way you'll see how to divide the hexagon into a rectangle (not necessarily a square), and two triangles - which, of course, you can combine again to form the hexagon.

Two trapezoids can make up a hexagon.
a trapezoid
a square ----------- Assuming it's a regular hexagon, it can be one of two shapes depending on whether you cut it in half on a side or on a vertex. On a side, it is an irregular pentagon. On a vertex, it is a trapezoid (quadrilateral).

It is a square with a right angle triangle attached to it having the same height as the square.
Oh, dude, let me break it down for you. So, a trapezoid has 4 sides while a hexagon has 6 sides. To form a hexagon, you need 3 trapezoids because if you try to fit 4 trapezoids together, you're just gonna end up with a wonky shape that's not a hexagon. So, it takes 3 trapezoids to make 4 hexagons. Easy peasy!
A trapezoid and a triangle can make a triangle or another trapezoid, among others.
Minimally, two (2) trapezoids are necessary to create a hexagon. (This solution comes from drawing a line straight across the center of the hexagon.) Most numbers (if not all) greater than two are also feasible, but with more finagling.
