Question 11
In the given figure, lines l and m intersect each other at a point. Which of the following is false?

(a) $\angle a=\angle b$
(b) $\angle d=\angle c$
(c) $\angle a+\angle d={180}^{\circ }$
(d) $\angle a=\angle d$

Answer 1

From the given figure it is clear that,$\angle a=\angle band\angle c=\angle d$
Also ,$\angle a+\angle d={180}^{\circ }$
and$\angle b+\angle c={180}^{\circ }$
