A)∠5 is an acute angle (40º) B) ∠2 is an obtuse angle (140º) C) ∠2 + ∠5 = 180° forms a supplementary angle. therefore, forms a straight line D) If a transversal intersects two parallel lines, then the interior angles on the same side of the transversal are supplementary. E) If a transversal intersects two lines and the interior angles on the same side of the transversal are supplementary, then the lines are parallel.

this is a little confusing as I compose it, but I am sure it somewhat makes sense: ∠2 is congruent to ∠1 since ∠2 and ∠5 forms a straight line or a supplementary angles (180º) then ∠4 must be congruent to ∠1 and since ∠1 is congruent to ∠2 then ∠1 and ∠5 must also be supplementary angles, which proves that line a and b are parallel

a proof starts with whats 'Given' so we can simply put the reason 'Given' for a and b.

similarly we wil be good if we just put fill the blanks c,d, and e wid approproate reasons i guess

rephrasing: A) given ∠5 in line b is an acute angle (40º) B) another given ∠2 in line a is an obtuse angle (140º) you are right about filling out the blanks, but I am not sure if the sentences D and E are even appropriate to state

:) c, your reason is good : 'supplementary angles add up to 180' d, we can simply fill wid : ' by Definition of sameside interior angles' e, we can fill wid : 'by Converse of sameside interior angles theorem'
