The triangle and rhombus pattern block shapes can be combined to make up a trapezoid.
No, you'll get 4 sides if combine a triangle and 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!

triangle and rhombus.
A trapezoid and a triangle can make a triangle or another trapezoid, among others.
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 how you combine them.You could have a trapezoid or a pentagon.

No. A trapezoid is not a triangle at all
