HELP PLZ

see explanation

Step-by-step explanation:

If the ratios of the 3 pairs of corresponding sides of the 2 triangles then the triangles are similar.

AB : DE = 4 : 2 = 2 : 1

BC : EF = 6 : 3 = 2 : 1

AC : DF = 2 :1

The ratios of the corresponding sides are equal, thus

Δ ABC is similar to Δ DEF ( SSS postulate )

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
