Answer 2

Answer:-

a) SAS

Step-by-step explanation:

Given:-

AB = AC

BAD = CAD

BD= DC( We PROVED)

and by one of the Triangle property B = AC,So BD = DC

Our answer:-

We got two sides One angle:-

So,That two Triangles are congruent by SAS congruency.

∆ ADB ≅ ∆ ADC

Additional Information:-

• In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
• There are four types of congruency
• They are:-
• Side Side Side (SSS) The three sides of one triangle are respectively equal to the three sides of the other triangle.
• Side Angle Side (SAS) ...
• Angle Side (AAS) ...
• Right angle Hypotenuse Side (RHS)
