Answer:
25) [tex]\overline{HF} \cong \overline{HF}[/tex]
26) [tex]\overline{SU} \cong \overline{EU}[/tex]
27) Yes, Two triangles are congruent, because of SSS (Side-Side-Side).
28) No, Both two triangles are not congruent. (There is only two sides and not a third one as a side or angle on a triangle).
29) Yes, Because those three numbers 9, 15, 10 can form a triangle.
[tex]9 + 15 > 10 =[/tex] True
[tex]9 + 10 > 15 =[/tex] True
[tex]15 + 10 > 9 =[/tex] True
30) No, Because those three numbers 18, 10, 6 can't form a triangle.
[tex]18 + 10 > 6 =[/tex] True
[tex]18 + 6 > 10 =[/tex] True
[tex]10 + 6 > 18 =[/tex] False
