Answer:
Devon use [tex]\frac{XZ}{TV}[/tex] instead of [tex]\frac{TV}{XZ}[/tex] in his reason. So, we can say that triangles are not similar.
Step-by-step explanation:
If two triangles are similar then their corresponding sides are proportional.
If triangle TUV and XYZ are similar, then
[tex]\frac{TU}{XY}=\frac{UV}{YZ}=\frac{TV}{XZ}[/tex]
The reason given be Devon is
[tex]\frac{TU}{XY}=\frac{UV}{YZ}=\frac{XZ}{TV}[/tex]
He use the correct concept, that the corresponding sides of similar triangle are proportional. But he use [tex]\frac{XZ}{TV}[/tex] instead of [tex]\frac{TV}{XZ}[/tex] in his reason.
Therefore his reason is incorrect. So, we can say that triangles are not similar.
