Question

PLEASE Help!

You have this information about ΔABC, ΔDEF, and ΔGHI:

AB = GH

BC = EF = HI

m∠B = m∠D

m∠B = m∠H

Which triangles must be congruent?

-ΔABC, ΔDEF, and ΔGHI

-ΔABC and ΔDEF only

- ΔABC and ΔGHI only

-none of the triangles

Answer 1

Two triangles are congruent if they have: exactly the same three sides and; exactly the same three angles. the information above is not sufficient for telling there are congruent triagles
so the possible answer is
-none of the triangles
