Assertion (A): If three angles of a triangle are equal to the corresponding three angles of another triangle, then the triangles are congruent.

Reason (R): Two triangles are said to be congruent, if and only if, one of them can be made to superimpose on the other so as to cover exactly.

1. A is true, R is false

2. A is false, R is true

3. Both A and R are true

4. Both A and R are false

Assertion (A): In △ABC, D is a point on side BC. AB + BC + AC > 2AD

Reason (R): Sum of two sides of a triangle is greater than the third side.

1. A is true, R is false

2. A is false, R is true

3. Both A and R are true

4. Both A and R are false
