Answer: The first and fourth pair of polygons are similar.


Step-by-step explanation:

If two polygons are similar then their corresponding sides are proportional.

Let's check

  • In the first pair there are two rectangles and their dimensions are proportional as

\frac{22}{13.75}=\frac{16}{10}=1.6

  • In the second pair there are right triangles but their dimensions are not proportional as

\frac{18}{8}=2.25 and \frac{30}{17}=1.76

  • In the third pair there is one isosceles triangle and other is equilateral triangle, which can not be similar as they have different type of triangles.
  • In the fourth pair there are two right trapezoid and their dimensions are proportional as

\frac{7.5}{3}=\frac{30}{12}=\frac{12.5}{5}=\frac{20}{8}=2.5
