Step 1
For any two triangles to be similar
(1) The corresponding angles of both the triangles should be equal
(2) The corresponding sides of both the triangles should be in proportion to each other.
Step 2
In the given triangles, $\mathrm{\angle }SUT=\mathrm{\angle }DUE$ (vertically opposite angles)
The ratio of sides,
$\frac{SU}{UD}=\frac{49}{21}2.333$
$\frac{TU}{UE}=\frac{73}{31}2.354$
As we see that the sides are not in proportion, so the triangles are not similar.
