Similarity s
Giving the following triangles
From the figure
Length IJ = Length HF
Length IK = Length = HG
Length JK = Length FG
Secondly, we need to find the scale factor
Since thet are both similar
[tex]\begin{gathered} \frac{HF}{IJ}\text{ = }\frac{HG}{IK}\text{ = }\frac{FG}{JK} \\ \frac{6}{4}\text{ = }\frac{7.5}{1.5}\text{ = }\frac{9}{6} \\ 1.5\text{ = 1.5 = 1.5} \end{gathered}[/tex]They all have a common scale factor
[tex]\text{Therefore }\Delta IJK\text{ }\cong\Delta HFG[/tex]
