Therefore, triangle \(ABC \) and triangle \(EFG\) are similar.
\(A'B'C'\) is the image of \(ABC \) under an enlargement at centre \((-2,-1)\) with a scale factor of \(\dfrac{3}{2}\).
\(R'S'T'U'\) is the image of \(RSTU\) under an enlargement at centre \((13,10)\) with a scale factor of \(\dfrac{1}{3}\).
\(L'M'N'\) is the image of \(LMN\) under an enlargement at centre \((2,-5)\) with a scale factor of \(-2\).
