Test: Congruence of Triangles - Class 7 MCQ

When 2 angles are equal in measurement, they are said to be congruent.

We have ASA ,SSS,SAS and RHS are congruence criterions.

When you join the line DE and EF you will find a common vertex E , which is the included angle.

In the triangles we have AB=PQ,BC=QR and AC=PR , so we write the name of the triangles such that the corresponding sides are equal, ie, AB=PQ so it will beABC ≅ PQR

In a congruence , triangles’ name are written such that the corresponding angles of both the triangles are equal, meaning that ∠D=∠B,∠E=∠C and ∠F=∠A. So , ∠C is the correct answer.

In a congruence , triangles’ name are written such that the corresponding angles of both the triangles are equal, meaning that ∠D=∠A,∠E=∠C and ∠F=∠B. So , ∠B is the correct answer.

From above diagram, it is clear that ∠C corresponds to ∠P
