Frequently Asked Questions
What is SSS similarity?
Side-Side-Side similarity means all three pairs of corresponding sides are in the same ratio. If that ratio matches for all three side pairs, the triangles are guaranteed similar, regardless of their angles.
Does the order of sides matter?
Yes, sides must be matched to their actual corresponding side in the other triangle, for example the shortest side of triangle 1 to the shortest side of triangle 2, not compared arbitrarily.
What if only two of the three ratios match?
Then the triangles are not similar. All three corresponding side ratios must match for SSS similarity; two matching ratios with a third that does not match means the triangles have a different shape.
