Devon says that triangles TUV and XYZ are similar because TU/XY UV/YZ XZ/TV what is wrong with his reasoning?

jeka57 [31]

Answer:

Devon use $\frac{XZ}{TV}$ instead of $\frac{TV}{XZ}$ 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

$\frac{TU}{XY}=\frac{UV}{YZ}=\frac{TV}{XZ}$

The reason given be Devon is

$\frac{TU}{XY}=\frac{UV}{YZ}=\frac{XZ}{TV}$

He use the correct concept, that the corresponding sides of similar triangle are proportional. But he use $\frac{XZ}{TV}$ instead of $\frac{TV}{XZ}$ in his reason.

Therefore his reason is incorrect. So, we can say that triangles are not similar.
