For two given triangles, ΔABC and ΔPQR, the number of possible matchings are

If ∆ ABC ≅ ∆ PQR, then the value of ∠A will be, 

∆ PQR is congruent to ∆ STU (in figure), then length of TU is ___________.

Congruent triangles are triangles that have same size and shape. This suggests us that the corresponding sides are equal and corresponding angles are equal.
When two triangles are congruent, all of their corresponding sides and angles are equal.

If, for ∆ ABC and ∆ DEF, the correspondence CAB and EDF gives a congruence, then false statement is 

If ∆ ABC and ∆ DBC are on the same base BC, AB = DC and AC= DB, then __________gives a congruence relationship. 

If ∆ ABC ≅ ∆ PQR, then any ∠B correspond to  

The symbol of correspondence is  

The double-sided arrow symbol is used to denote correspondence. 

 In SAS congruency  

In SAS congruence, triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles.

In the given figure, if ,  then ___________. 

Two sides and the included angle are congruent in __________ postulate. 

SAS congruence is the term which is also known as Side Angle Side congruence. In this, triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles. 

Identify the postulate in the given figure. 

If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are _________. 

Identify the type of postulate in the given diagram. 

In the given triangle ABC, AB = AC, then the angles are __________. 

If three sides of one triangle is congruent to another triangle, then they satisfy ___________ congruence. 

If all three sides of one triangle are equal to the three equal sides of another triangle, the two triangles are congruent according to the same criterion.

If the hypotenuse and one leg of a right triangle are equal to another right triangle, then it is ________.
