SSS
SSS, also known as Side-Side-Side, is a criteria used to prove that two triangles are congruent
SSS, also known as Side-Side-Side, is a criteria used to prove that two triangles are congruent. In order to apply the SSS criterion, we need to show that all three sides of one triangle are congruent to the corresponding three sides of another triangle.
To prove that two triangles are congruent using the SSS criterion, we need to follow these steps:
1. Identify the triangles: Start by labeling the given triangles. Let’s say we have triangle ABC and triangle XYZ.
2. Compare corresponding sides: Look at the three sides of triangle ABC and triangle XYZ and compare them. Let’s say AB is congruent to XY, BC is congruent to YZ, and AC is congruent to XZ.
3. Apply the SSS criterion: If all three pairs of corresponding sides are congruent, i.e., AB ≅ XY, BC ≅ YZ, and AC ≅ XZ, then we can conclude that triangle ABC is congruent to triangle XYZ using the SSS criterion.
4. State the congruence statement: Finally, write the congruence statement to show the congruence of the two triangles. In this case, it would be triangle ABC ≅ triangle XYZ.
Remember, the order in which the sides are stated is important. For example, if we had stated AB ≅ XY, BC ≅ XZ, and AC ≅ YZ instead, it would not satisfy the SSS criterion for congruence.
It is also worth noting that the SSS criterion only applies to showing congruence between two triangles. It does not apply to other polygons or shapes.
I hope this explanation helps you understand the SSS criterion for proving triangle congruence in mathematics. If you have further questions, feel free to ask!
