The two figures are congruent because dilation s used to map figure 1 onto figure two
What is dilation?
dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller.
From the figure shown you can see that PQRS is dilated to produce EFGH since the shapes are similar in nature but the quadrilateral EFGH is an enlarged form of PQRS
Hence we can conclude that the two figures are congruent because dilation is used to map figure 1 onto figure two
