Final answer:
The transformation from trapezoid EFGH to trapezoid JKLM is a dilation that changes the size of the figure without changing its shape.
Step-by-step explanation:
The transformation from trapezoid EFGH to trapezoid JKLM is a dilation.
A dilation is a type of transformation that changes the size of a figure without changing its shape. In a dilation, each point of the original figure moves along a straight line towards or away from a fixed point called the center of dilation.
For example, if we scale up trapezoid EFGH to create a larger trapezoid JKLM, we are performing an enlargement dilation. Conversely, if we scale down trapezoid EFGH to create a smaller trapezoid JKLM, we are performing a reduction dilation.
