Step 1
Given;
Step 2
In the figure;
[tex]\begin{gathered} Both\text{ triangles share the same side XW} \\ \end{gathered}[/tex][tex]Also\text{ sides XY }\cong XW\cong XZ(Given)[/tex][tex]Also\text{ YW}\cong WZ\cong10\text{ \lparen Given\rparen}[/tex]
Thus; the triangles are congruent by Side Side Side (SSS)
Since all congruent triangles are similar, then it follows that the triangles are similar.
Answer; They are similar
