25. Exemplar exercise problems II

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:

 

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