Since ∆ABC ~ GHI, therefore their corresponding side lengths would be proportional to each other. This implies that the ratio of their corresponding lengths are equal.
This also means that the same scale factor can be multiplied with any side length of ∆ABC to get the corresponding side length of ∆GHI.
The scale factor = HI/BC = 25/10 = 2.5
The side length that corresponds to z is AB which is 8 m long.
z = 8*2.5
✅Side length z = 20 m
Corresponding angles of similar triangles are congruent to each other.
