4.6 SSS Triangle Congruence
Here you’ll learn how to prove that two triangles are congruent given only information about the side lengths of the
triangles.
What if your parents were remodeling their kitchen so that measurements between the sink, refrigerator, and oven
were as close to an equilateral triangle as possible? The measurements are in the picture at the left, below. Your
neighbor’s kitchen has the measurements on the right, below. Are the two triangles congruent? After completing
this Concept, you’ll be able to determine whether or not two triangles are congruent given only their side lengths.
