# In the Fig; we have $\angle ABC=\angle ACB, \angle 3=\angle 4$. Then:

$\angle 1 = \angle 2$

##### SOLUTION
Given, $\angle ABC =\angle ACB$, $\angle 3 = \angle 4$
Now,
$\angle ABC = \angle ACB$
$\angle 1 + \angle 4 = \angle 2 + \angle 3$
But, $\angle 3 = \angle 4$ (Given)
Thus, $\angle 1 = \angle 2$

You're just one step away
