The transformation Renec used to create triangle B is a dilation.
Step-by-step explanation:
The correct answer is A. Dilation.A dilation is a transformation that changes the size of the figure while preserving its shape. In a dilation, each point of the original figure is multiplied by a scale factor. This is done by multiplying the coordinates of each point by the scale factor.In this case, Renec used a dilation to create triangle B. The corresponding sides of the two triangles are proportional, indicating a dilation. Therefore, the correct transformation is a dilation
