Answer:
1) Dilation of ΔLMN by scale factor of 1/2
2) Translation following this rule
Explanation:
The Set of transformations applied to prove the similarity between this pair of triangles is:
![\bigtriangleup PQR \sim \bigtriangleup LMN](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tc4ldm8j7l3o72c7b3z6xcpnxattt3ejfk.png)
1) Dilation of ΔLMN by scale factor of 1/2
Shrinking figures, their factor is <1
![D=((1)/(2) x, (1)/(2)y)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/gv3fqllmavhqgevhsh5vhmk5rtfyvprff4.png)
2) Translation following this rule
![(x-0.5,y+2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/hyzd98e9zg0gu1houbvd6c2uxp79jolfat.png)
ΔL'M'N' translated will be ΔPQR
Their angles remain with the same value. Therefore they are similar.
