Which of these triangle pairs can be mapped to each other using a translation and a rotation about point A? Triangles Q R A and K P A are connected at point A. Triangle K P A is rotated to form triangle Q R A. Triangles Q R A and K P L are shown. Triangle Q R A is reflected and then shifted to the right to form triangle K P L. Triangles Q R A and K P L are shown. Triangle Q R A is reflected and then shifted to the right to form triangle K P L. Triangles Q R A and K P L are shown. Triangle Q R A is rotated about point A and then is shifted down and to the left to form triangle K P L.

step-by-step explanation:

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'.
