Lyle graphs triangle ABC on coordinate axes. He performs two transformations on this figure that would result in the congruent triangle XYZ. Which series of transformations did Lyle most likely use?

A translation left and then a dilation with a scale factor of 3

A dilation with a scale factor of 2.5 and then a rotaion 180 degrees counterclockwise.

A rotation 90 degrees clockwise and then a reflection across the y-axis.

A reflection across the x-axis and then a dilation with a scale factor of 0.25

It will be larger than the original triangle

It will be congruent to the original triangle

It will be smaller than the original triangle.

It will be a different shape than the original triangle.
