1) triangleTRS ~ triangleTPQ; SSS ~
2) triangleTRS ~ triangleTPQ; SAS ~
3) triangleTRS ~ trianglePQR; SAS~
4) The triangles are not similar.
need help with this one!!! thanks.

Answer:

2) triangleTRS ~ triangleTPQ; SAS ~

Step-by-step explanation:

[tex] TR = TP + PR = 42 + 6 = 48\\

TS = TQ + QS = 28 + 4 = 32\\

In \:\triangle TRS\: and \:\triangle TPQ\\

\frac{TR}{TP} = \frac{48}{42} = \frac{8}{7} ....(1)\\\\

\angle RTS \cong \angle PTQ.. (common \: \angle)... (2)\\\\

\frac{TS}{TQ} = \frac{32}{28} = \frac{8}{7} ....(3)\\\\[/tex]

From equations (1), (2) & (3) it is obvious that:

[tex] \therefore \triangle TRS \sim\triangle TPQ... (SAS \: Postulate) [/tex]
