EXPLANATION
From the given diagram;
we have two triangles,
The size of the bigger triangle is;
[tex]\begin{gathered} 3+1=4 \\ 2.25+0.75=3 \\ \end{gathered}[/tex]comparing the two given sides of the bigger triangle, we have;
[tex]\frac{4}{3}=1.333[/tex]while that of the smaller triangle is;
[tex]\frac{1}{0.75}=1.3333[/tex]Therefore the sizes of the two sides are equivalent
now, since the angle given is an included angle, we can say that they are similar triangle by
