Pls help me im actually crying rn

Which of these triangle pairs can be mapped to each other using two reflections?

In the diagram, the ratios of two pairs of corresponding sides are equal to prove that almn - axyz by the sas similarity theorem, it also needs to be shown that x 6 z un z zz un = 2x zləzz lezy

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
