easy draw a trapezoid (4 sided) and add a triangle to one of the bottom sides (3 sides) ___ / __\ \ /
It make a line of symmentry and something else
by 1 parallelogram and a triangle
you get a trapezoid
Depending on their size and degree of overlap, they can make any number of shapes up to a 16-sided polygon.
A trapezoid and a triangle can make a triangle or another trapezoid, among others.

put the triangle so that one of the sides is against the long side of the trapezoid.

A trapezoid and a triangle make a paralellogram.
No because a trapezoid has 4 sides and a triangle has three if a trapezoid had three then it would be a triangle. If you had 3 trapezoids you could make a triangle!
Depending on their size and degree of overlap, they can make any number of shapes up to a 16-sided polygon.
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!
Bigger triangle, a parallelogram or a pentagon.
