Definition of Congruency of Triangles

_______________________________

$\large\bf\red{ANSWER➽}$

Congruency of Triangles can be defined as the Principle which supposed that Given two or more then two triangles are identical to each other or one is blueprint of another triangle.

How to prove Congruency:-

If two triangles have their Corresponding sides equal and Corresponding angles are also equal then it is Prooved that both Triangles are Congruent to each other.

By using rules of Congruency:-

Two Triangles are Congruent if either one of these rules will be followed by both Triangles:-

SAS rule of Congruency.

SAS stands for Side Angle Side rule of Congruency.(IF two sides and one angle are equal)

SSS rule of Congruency.

SSS stands for Side Side Side rule of Congruency.(If all side are equal)

ASA rule of Congruency.

ASA stands for Angle Side Angle rule of Congruency.(If two angles and one side are equal)

AAS rule of Congruency.

AAS stands for Angle Angle Side rule of Congruency.(If two angles formed by hypotenuse with other two sides and one side are equal)

$\large\bf\green{EXAMPLE➠}$

(SEE THE ATTACHED PIC ABOVE)

Let ABC and DEF are two triangles,

Given,

AB=DE

BC=EF

AC=DF

and:-

All angles are equal .......

Note:-

In this example all rule of Congruency are applied...So you can use either of these.

Hence,

ABC≈DEF...
