Question

In a triangle ABC,  ∠A=300, ∠B=400 where AB=5cm. In a triangle PQR , ∠P= 300, ∠Q=400 where PQ=5cm. The two triangles are congruent under

​

Answer 1

Answer:

Two triangles are congruent if their corresponding sides are equal in length and their corresponding angles are equal in size.

In the first option, DF=5 cm but ∠F is not equal to 60

∘

.

In the third and the fourth options, the length of DE



=5cm, since it is not defined.

In the second option, DF=5cm and ∠E=60

∘

is satisfied.
