They gave you the lengths showing each side of the original triangle is congruent to each side of the new triangle. There is no information to show if the triangle was rotated or reflected, so although it is possible that it was, we can't really tell. All we know is the triangles are congruent.

HELP ASAP 40 POINTS
AleksandrR [38]

Given:

The sequence is -8, -12, -16.

To find:

The nth and 52th term  of the given sequence.

Solution:

We have,

-8, -12, -16

It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is

r=a_2-a_1

r=-12-(-8)

r=-12+8

r=-4

The nth term of an AP is

a_n=a+(n-1)d

Where, a is first term and d is common difference.

Putting a=-8 and d=-4, we get

a_n=-8+(n-1)(-4)

a_n=-8-4n+4

a_n=-4-4n

Putting n=52, we get

a_{52}=-4-4(52)

a_{52}=-4-208

a_{52}=-212

Therefore, the equation for the nth term of the given sequence is a_n=-4-4n and the 52nd term of the sequence is -212.
