The original object and its translation<span> have the same shape and size, and they face in the same direction. A </span>translation<span>creates a figure that is congruent with the original figure and preserves distance (length) and orientation (lettering order). A </span>translation<span> is a direct isometry.</span>
Given:
A rectangular piece of cloth (dimensions):
L = length of the rectangle
W = width of the rectangle
The area of the rectangle is:
A = L x W
If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:
A (one sail) = 1/2 (L x W) <span />
If I would be a student my answer would be:
"You are a rhombus".
