Question

In figure it is given that traingleABDis congruent to triangle BCA, name the critirea by which the triangles are congruent
please give the right answer​

Answer 1

Step-by-step explanation:

From the figure angle D and Angle C are same

means angle D= angle C

and AB = AB common sides

also AD = BC ( given)

hence tringle is congruent by SAS

If the angle D = angle C=90°

it will congruent by RHS

Answer 2

Here, as triangle ABD is congruent to triangle BCA

Then side AB = Side AB ( common side)

Side BD = Side CA

Side AD = Side BC

Angle D = Angle C = 90° (given)

So it is SAS test of similarity and if the 90° is not given and marked by you it is SSS test of similarity
