The generalization of a triangle, trapezoid, and pentagon can be understood through the concept of polygons. A triangle is a three-sided polygon, a trapezoid is a four-sided polygon (quadrilateral) with at least one pair of parallel sides, and a pentagon is a five-sided polygon. More broadly, these shapes are all specific instances of n-gons, where "n" represents the number of sides and vertices in the polygon, allowing for a classification based on the number of sides and the relationships between them.
Bigger triangle, a parallelogram or a pentagon.
They are all polygons.
-- trapezoid -- triangle -- irregular quadrilateral -- pentagon -- hexagon etc.
A scalene triangle, A trapezoid, an irregular pentagon.
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!
