1. It is given that \(\Delta ABC \sim \Delta DFE\), \(\angle A = 30^\circ\), \(\angle C = 50^\circ\), \(AB = 5 \ cm\), \(AC = 8 \ cm\) and \(DF = 7.5 \ cm\). Then, the following is true:

\(DE = 12 \ cm\), \(\angle F = 100^\circ\)
\(EF = 12 \ cm\), \(\angle D = 100^\circ\)
\(DE = 12 \ cm\), \(\angle F = 50^\circ\)
\(EF = 12 \ cm\), \(\angle D = 30^\circ\)

2. If in triangles \(ABC\) and \(DEF\), \(\frac{AB}{DE} = \frac{BC}{FD}\), then they will be similar, when

\(\angle A = \angle D\)
\(\angle B = \angle D\)
\(\angle B = \angle E\)
\(\angle A = \angle F\)
