Two opposite sets of parallel lines.
Not all trapezium are Isosceles.

No, apart from the fact that there is no such word. The word isosceles is derived from "equal legs" and, in the context of a triangle refers to the two sides or legs of an isosceles triangle in its conventional aspect. In the case of quadrilaterals, any of the following have equal legs: a kite, arrowhead, an isosceles trapezium, a rhombus, square, rectangle, and at a stretch a parallelogram. All in all, then the adjective would not be particularly helpful in narrowing down the possibilities.

A "leg" is the term used in geometry to describe the two sides that are equal in length in an isosceles triangle.

Observation.
"Isosceles" is a type of triangle. Triangles are two-dimensional.
Production management has been the traditional term used to describe all the activities managers do to help their firms create goods.
No because they both have different geometrical properties although they both belong to class of 4 sided shapes known as quadrilaterals
