Bryan has a square parcel of land that is 120 yards long and 120 yards wide. the land is planted with bermuda grass and surrounded by a fence. so that his cattle will not ruin the grass, bryan decides to split the field into two halves and rotate his cattle on the land every 30 days. he plans to build a fence diagonally across the field. how many feet of fencing will bryan need to split the parcel of land in half? round your answer to the nearest yard.

there is no question content here, but you for the free points! : d

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'.
