In each of the following questions, a statement of Assertion (A) is given followed by a corresponding statement of Reason (R) just below it. Of the statements, mark the correct answer as

Assertion : In all given figure, if l || m, then ΔABC is an isoceles triangle.

Reason : If all sides of a triangle are equal, then it is an isosceles triangle.

A If both assertion and reason are true and reason is the correct explanation of assertion

B If both assertion and reason are true but reason is not the correct explanation of assertion

C If assertion is true but reason is false

D If assertion is false but reason is true.

here reason is false because if all sides are equal means it is equilateral triangle and not isosceles. answer is C

## Ans 1:

If the Triangle ABC a isosceles triangle then the assertion is true but the Reason is If all sides of a triangle are equal then it is an isosceles triangle. But it is general that if all the sides of a triangle are equal then it is a equilateral triangle.
