Answer:
On the first page: The two trapezoids on the left are similar.
On the second page: The two rectangles on the right are similar.
Step-by-step explanation:
Similar shapes have corresponding sides in a constant proportion.
The trapezoids on the left of the first page have a scale factor of 2.5 between the smaller and larger trapezoid between all corresponding sides, therefore are similar.
The rectangles on the right of the second page have a scale factor of 1.6 between the smaller and larger rectangle between all corresponding sides, therefore are similar.
