Which of the following statements proves that A F is parallel to EF?

Options:
1. m∠BFG + m∠GFC = 180°
2. m∠DEB + m∠BEF = 180°
3. m∠GFC + m∠ICF = 180°
4. m∠FCA + m∠AEF = 180°
5. None of these options are correct.

Here is another question that I need answered if you like helping people (giving more points for that one):

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
