[i][b]So....[/b][/i][br][br]If 3 sides of one triangle are congruent to 3 sides of another triangle, can we say that those 2 triangles are congruent? Fully explain why or why not.
By reflecting and translating the original triangle, it is mapped onto the new triangle. Since they are rigid motions, the original triangle is congruent to the new triangle.
