Question

How many parts of two triangles do we need to check congruency​

Answer 1

Step-by-step explanation:

SAS (Side-Angle-Side): If two pairs of sides of two triangles are equal in length, and the included angles are equal in measurement, then the triangles are congruent. SSS (Side-Side-Side): If three pairs of sides of two triangles are equal in length, then the triangles are congruent.

Answer 2

Answer:

There are some criterias to prove congruency. They are:

1. ASA- Angle Side Angle
2. SAS- Side Angle Side
3. SSS- Side Side Side

So you need three parts of a triangle to check congruency.
