What are some methods that can prove triangles congruent?

Answer 1

• SSS - Side-Side-Side

All three corresponding sides of the triangles have the same length

• AAS - Angle-Angle-Side; ASA - Angle-Side-Angle

Two corresponding angles are equal and a corresponding side is equal

• SAS - Side-Angle-Side

Two corresponding sides have the same length and the enclosed angle is the same.

Note: it is important that the angle is the one between the corresponding sides of equal length.

• RHS - Right_angle-Hypotenuse-Side

In a right angled triangle the hypotenuse and a corresponding side must be equal.
