Two equal lengths and two equal angles.
Only when it has 3 unequal acute angles and 3 unequal sides that it is then a scalene triangle.
A scalene trapezium is like a scalene triangle since all the sides are not the same
That depends on the sizes of its 4 interior angles but there are 2 triangles in a trapezium
They can tesselate - provided they are the correct shapes.

yes
No because they both have different properties inasmuch that a triangle has 3 sides whereas a trapezium has 4 sides.
