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.
Well, honey, if you want to find a 4-digit number where the digits are reversed when multiplied by 9, the number you're looking for is 1089. That's the only number that plays nice and keeps its digits in line when you multiply it by 9. So, there you have it - 1089 is the magic number you're after.

In parallelogram ABCD, AC=BD. Is ABCD a rectangle?
the emergency brake; no it is not the emergency brake it starts with a D as in ABCD, Acceleration, brake, clutch and D
