Answer 1

OK first you use Corresponding Parts of Congruent Triangles are Congruent so that gives you line IN is congruent to line MN. Then you can prove that triangle DIN is congruent to triangle OMN by the Side Side Side Postulate. (BTW the first thing is abbreviated CPCTC.) Good luck and please pick me for best answer!

Answer 2

Given: Triangle ANM congruent to Triangle ANI
so Line IN is congruent to Line MN

Line DI is congruent to Line OM
DI=OM

Line ND is congruent to Line NO
ND=NO

Prove: Triangle DIN is congruent to Triangle OMN
DI = OM (given)
ND=NO (given)
IN=MN (proved)
for triangle, 3 lines are equal (SSS)


So:
Triangle DIN is congruent to Triangle OMN

Answer 3

compare triangles DIN and OMN

DI = OM (given)

ND = NO (given)

IN = MN (since it is given that triangles ANI and ANM are congruent)

so all the sides of triangle DIN are congruent to all the sides of triangle OMN.

triangles DIN and OMN are congruent

Answer 4

IN=MN congruent triangle parts
DIN=OMN SSS=SSS
