Bella wants to use rigid transformation to show that triangle GHI congruent to triangle LKJ to illustrate the SSS triangle congruence criterion. Which of the following could she do first?
To illustrate the SSS triangle congruence criterion, Bella could do the following first:
1. Verify that the lengths of corresponding sides in both triangles are equal. This can be done by measuring the lengths of sides GH, HI, and IG, and comparing them to the lengths of sides LK, KJ, and JL.
By showing that the corresponding sides of the triangles are congruent, Bella can establish one part of the SSS (Side-Side-Side) criterion for triangle congruence.
