प्रश्न
In the given figure, lines l and m intersect each other at a point. Which of the following is false?
विकल्प
∠a = ∠b
∠d = ∠c
∠a + ∠d = 180°
∠a = ∠d
उत्तर
∠a = ∠d
Explanation:
∠a = ∠b ......[Vertically opposite angles]
∠d = ∠c .....[Vertically opposite angles]
∠a + ∠d = 180° ......[Linear Pair]
But ∠a ≠ ∠d
