Answer:

Quadrilateral FSHB∼quadrilateral KTWJ.

Step-by-step explanation:

Given two quadrilaterals we have to prove these two similar.

The two quadrilaterals are similar if the corresponding sides of these are proportional then only the quadrilateral are proportional i.e

∴ $\frac{FS}{KT}=\frac{SH}{TW}=\frac{HB}{WJ}=\frac{BF}{JK}$

If the above condition satisfied then the quadrilateral are similar.

Let us find these ratios

$\frac{FS}{KT}=\frac{28}{21}=1.333$

$\frac{SH}{TW}=\frac{24}{18}=1.333$

$\frac{HB}{WJ}=\frac{18}{13.5}1.333$

$\frac{BF}{JK}=\frac{18}{13.5}1.333$

All ratios are equal.

Hence, the corresponding sides and angles of these two quadrilaterals are proportional implies that these two are similar i.e quadrilateral FSHB∼quadrilateral KTWJ.
