Will give brainlist worth 50 ! ! write expressions equaling 1-100 using only the numbers 2,0,1, and 9. you may use the operations of addition, subraction, multiplication, and division, as well as "juxtaposition" (putting two numbers side by side as in 12 or 91), exponents, square roots, decimal points, and factorials. if you use exponents, the must be a 1,0,2, or 9. all four digits must be used once in each expression.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
