You can put this solution on YOUR website!
im not to good with the wording for the proof but
if angle A is supplementary to angle C
then angle A+ angle C = 180degrees
if angle B is supplementary to angle C
then angle B+ angle C= 180degrees
so then angle A+ angle C = angle B+ angle C
so angle A = angle B
this mostlikely isnt the write way to write it but im sure u can find the right properties for my explaination to put in order
