$\textbf{Answer is in Attachment !}$

Answer 2

$\underline{CRITERIA\: OF \:SIMILARITY \:OF\: TRIANGLES}$

$\textb{1] AAA\: SIMILARITY\: OF\: CRITERION:(or equi- angular \:criterion) }$

The corresponding angles of two Triangles are equal then their corresponding sides are proportional and hence the Triangles are similar

2] $\textb{SSS\: SIMILARITY \:OF\: CRITERION }$

In this Criterion the corresponding sides of two Triangles are proportional then their corresponding angles are equal then the Triangles are said to be similar

3] $\textb{SAS\: SIMILARITY\: OF\: CRITERION:}$

In this case if two sides and an included angle of One triangle are respectively equal to two side and included angle of another triangle then the two Triangles are said to be similar
