Study Notes
Congruent Triangles
Criteria for Congruent Triangles
SSS Criterion (Side-Side-Side)
- If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.
- This criterion ensures that the corresponding sides of the two triangles are equal.
ASA Criterion (Angle-Side-Angle)
- If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.
- The included side is the side between the two given angles.
SAS Criterion (Side-Angle-Side)
- If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.
- The included angle is the angle between the two given sides.
AAS Criterion (Angle-Angle-Side)
- If two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.
- The non-included side is a side that is not between the two given angles.
Note: These criteria are used to prove that two triangles are congruent, and they are all equivalent.
Congruent Triangles
Criteria for Congruent Triangles
SSS Criterion
- Three sides of one triangle are equal to three sides of another triangle, ensuring corresponding sides are equal.
ASA Criterion
- Two angles and the included side of one triangle are equal to two angles and the included side of another triangle.
- The included side is the side between the two given angles.
SAS Criterion
- Two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.
- The included angle is the angle between the two given sides.
AAS Criterion
- Two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle.
- The non-included side is a side that is not between the two given angles.
General Notes
- These criteria are used to prove that two triangles are congruent.
- All four criteria (SSS, ASA, SAS, and AAS) are equivalent.
