Mathematics

In the given figure, we have $$\angle 1=\angle 3$$ and $$\angle 2=\angle 4$$, then:


ANSWER

$$\angle A=\angle C$$


SOLUTION
Since $$\angle 1=\angle 3, \angle 2=\angle 4$$
$$\therefore \angle 1+\angle 2=\angle 3+\angle 4$$
$$\Rightarrow \angle BAD=\angle BCD\Rightarrow \angle A=\angle C$$.
