From the AAS property of congruency the side ab≅ac in the isosceles triangle.

What is the congruency of the triangle?

Congruency generally shows the similarities between two triangles or any other shape for the similarity of the two shapes they should have any three properties same like their three sides, Three angles or one angle two sides and so on.

Now for an Isosceles triangle abc given in the figure

[tex]\angle bad=\angle cad[/tex]

[tex]\angle abd=\angle acd[/tex]

[tex]ad=ad[/tex]   (common side)

So from the AAS property, the triangle [tex]\Delta bad=\Delta acd[/tex] are congruence

The side ab will also be equal to the side ac.

So from the AAS property of congruency is the side ab≅ac in the isosceles triangle.
