The transformation used to create K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.
What is transformation?
"Transformations are change in the original shapes on a coordinate plane by rotation, reflection or translation. "
What is reflection transformation?
"It is a transformation which produces mirror image of geometrical structure."
What is dilation?
"It is a transformation in which size of the geometrical structure is changed without changing its shape."
From given diagram,
we can observe that JK = 4 and J'K' = 2
This means the size of the triangle J'K'L' is reduced by 1/2
Also, it is reflected along x-axis.
This means, the transformation used to create triangle K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.
Therefore, the correct answer is option (B).
