NEED ANSWERED ASAP! Use transformations to explain how these 3 sets of triangles are congruent.
Use the names of the one or two transformations and explain your reasoning.

Step-by-step explanation:

a. reflect the shape across the y-axis, this is the fasted method to get each shape to lie on top of the other.

b. rotate triangle ABC 90 degrees counter-clockwise about the point c, shift the triangle one unit left and three units up.

c. reflect either shape about the x-axis and y-axis

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
