In order to answer that, I need to know the position of ABCD with respect tothe x-axis before the reflection process begins.But wait! What light through yonder window breaks ? ! On second thought, maybe I don't.If D is the point (x, y) before the reflection, then D' is the point (x, -y) after it.
Clockwise from 'a' it will be at the bottom right hand side and it will have 4 equal sides with 2 equal opposite acute angles and 2 equal opposite obtuse angles.
The perimeter of a trapezium is the summation of all its sides. So, if a, b, c and d were the sides of the trapezium, then the perimeter would be a plus b plus c plus d.

add all sides together :D
A B . . D C . . Parallelogram ABCD.
type in: "ABCD" in the input line.
Define abcd!
In parallelogram ABCD, AC=BD. Is ABCD a rectangle?
Two trapeziums and four rectangles.
the emergency brake; no it is not the emergency brake it starts with a D as in ABCD, Acceleration, brake, clutch and D
