Answer:
Step-by-step explanation:
In the figure attached there are two triangle PQR and STU have been given.
We have to prove both the triangle are similar.
If these two triangles will be similar if corresponding sides should have the same ratio.
[tex]\frac{PQ}{ST}=\frac{PR}{SU}[/tex]
[tex]\frac{20}{5}=\frac{12}{3}[/tex]
4 = 4
Hence the given triangles are similar
