Answer 1

For the vertical side, the lower part is three, and the top is congruent, so the whole side is 6. If we put the values together in proportion, we get \[\frac{ 3 }{ 6 }=\frac{ 5 }{ 10 }=\frac{ 4 }{ 8 }\]
Simplify them. If they are equal, then the side-side-side works. If they aren't equal, they aren't similar.

Answer 2

Oh okay thankyou!
