Step 1:
I'll solve this proof step by step using proper LaTeX formatting:

Step 2:
: Understand the Given Information

- $$\angle 1 \cong \angle 4
- \angle 3 and \angle 4 are supplements

Step 3:
: Define Supplementary Angles

- $$m\angle 3 + m\angle 4 = 180°
- Supplementary angles are two angles that sum to 180°

Step 4:
: Use the Congruence of \angle 1 and \angle 4

- Since $$\angle 1 \cong \angle 4$$, their measures are equal
- m\angle 1 = m\angle 4

Step 5:
: Algebraic Manipulation

- $$m\angle 1 + m\angle 2 = m\angle 3 + m\angle 4
- m\angle 1 + m\angle 2 = 180°

Step 6:
: Rearrange the Equation

- $$m\angle 2 = m\angle 3
- Substitute m\angle 1 = m\angle 4

Step 7:
: Conclusion

- Since their measures are equal, $$\angle 2 \cong \angle 3

Final Answer

\angle 2 \cong \angle 3 is proven.
