1.	In Fig., lines l and m intersect each other at a point. Which of the following is false? (a) ∠a = ∠b (b) ∠d = ∠c (c) ∠a + ∠d = 180° (d) ∠a = ∠d
Answer» (d) ∠a = ∠d ∠a ≠ ∠d ∠a = ∠b [because vertically opposite angles] ∠d = ∠c [because vertically opposite angles] ∠a + ∠d = 180^o

In Fig., lines l and m intersect each other at a point. Which of the following is false? (a) ∠a = ∠b (b) ∠d = ∠c (c) ∠a + ∠d = 180° (d) ∠a = ∠d

Answer»

(d) ∠a = ∠d

∠a ≠ ∠d

∠a = ∠b [because vertically opposite angles]

∠d = ∠c [because vertically opposite angles]

∠a + ∠d = 180^o
