# Which of the following properties are used to prove that triangles are congruent? asa sss aaa aas sas

Congruent triangles are those triangles that coincide with each other by repositioning or flipping.

## Answer: SSS, SAS, ASA, AAS properties are used to prove that triangles are congruent.

Let's find out the answer step by step.

**Explanation: **

Two triangles are said to be congruent if they follow either of the following properties:

SSS: If all the three sides of the two triangles are equal.

An example with the figure of SSS property is given below:

SAS: If two sides and the angle between them are equal.

An example with the figure of SAS property is given below:

ASA: When two angles and the side between them are equal.

An example with the figure of ASA property is given below:

AAS: When two angles and one non-included side are equal. (Similar to ASA property)
