congruent - SSSAnswer by Arteom, Friday December 10, 2010
This sentence can be complete as: After a congruence transformation the area of a triangle would be the same as it was before.
A ruler or a compass would help or aternatively use Pythagoras' theorem to prove that the diagonals are of equal lengths
That would be a postulate
Ah, what a lovely question! To show that triangles EFG and HIJ are congruent by Side-Side-Side (SSS), we would need to ensure that all three pairs of corresponding sides are equal in length. Additionally, the corresponding angles would also need to be congruent to fully demonstrate the congruence between the two triangles. Just remember to take your time, be gentle with yourself, and enjoy the process of exploring geometry.
