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.

To determine the coordinates of point D in trapezium ABCD, we need the coordinates of points A, B, and C, as well as the requirement that one pair of opposite sides (either AB and CD or AD and BC) are parallel. If AB is parallel to CD, then the y-coordinates of points A and B must equal the y-coordinates of points C and D, respectively. Alternatively, if AD is parallel to BC, then the x-coordinates of A and D must equal the x-coordinates of B and C. Please provide the specific coordinates of points A, B, and C for a precise answer.

add all sides together :D
A B . . D C . . Parallelogram ABCD.
type in: "ABCD" in the input line.
To solve the equation ( abcd \times 9 = dcba ), we can represent ( abcd ) as ( 1000a + 100b + 10c + d ) and ( dcba ) as ( 1000d + 100c + 10b + a ). This leads to the equation ( 9(1000a + 100b + 10c + d) = 1000d + 100c + 10b + a ). Through trial and error, you can find that ( a = 1 ), ( b = 0 ), ( c = 8 ), and ( d = 9 ) satisfy the equation, giving ( abc = 108 ) and ( d = 9 ).
Define abcd!
In parallelogram ABCD, AC=BD. Is ABCD a rectangle?
