We need to notice that SSSS does not exist as a method to prove that parallelograms are congruent
Counterexample
As we can see we have the same measure of the side of the intern angles of the figures are different therefore we can't use SSSS to prove congruence
36/48 simplified is 3/4
divide both by 12
36÷12
3
48÷12
4
There is so solution to this problem
Y + 0.4 = 2 .....subtract 0.4 from both sides
y = 2 - 0.4
y = 1.6 <==
