उत्तर
A is false but R is true.
Explanation:
Assertion:
- In a trapezium, only one pair of opposite sides is parallel.
- ∠A + ∠C = 180° can happen in some quadrilaterals that are not trapeziums.
- Also, this condition is only true if A and C are interior angles on the same side of a transversal between parallel lines not just any opposite angles.
Reason:
- This is correct by definition of a trapezium or trapezoid.
