Side Side Side or SSS criterion is a congruence postulate where the sides of one triangle are equal to the corresponding sides of another triangle. Learn more about the SSS, its theorem, formula, and …

SSS means Side, Side, Side. SSS is when we know three sides of the triangle, and want to find the missing angles.

SSS stands for Side-Side-Side theorem, which states that when all three sides of a triangle are equal to all three sides of another triangle.

Side-Side-Side (SSS) Rule Side-Side-Side is a rule used to prove whether a given set of triangles are congruent. The SSS rule states that: If three sides of one triangle are equal to three sides of another …

Dec 1, 2025 · The SSS criterion for triangle similarity states that if three sides of one triangle are proportional to three sides of another triangle, then the triangles are similar. In this concept, learn …

Definition: Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other. There are five ways to test that two triangles are congruent. This is one of them …

Jul 23, 2025 · SSS Criterion, which stands for Side-Side-Side congruence postulate, is a rule in geometry which says that if all three sides of one triangle are equal to the three corresponding sides …

In this lesson you’ll prove an important geometric fact: The Side-Side-Side Theorem (SSS). In Activity 1 you will practice by constructing and proving a simpler theorem.

Side Side Side postulate states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent. In diagram 1, you can see that all 3 sides of $$ …
