Statement 1: ∠2=∠4 .. Given
Statement 2: Measure of angle 2 = Measure of angle 4 = Alternate angles
Statement 3: ∠2=∠3 , Given Supplementary Angles
Statement 4 : ∠2+∠3=180 , Sum of supplementary angles is equal to 180 degree.
Statement 5: ∠1 and ∠4 are supplementary angles because angle of a straight line is equal to 180 degree.
Statement 6: Measure of angle 1 + measure of angle 4 = 180, sum of angles of supplementary angles is 180 degree.
Statement 7: ∠1+∠4= ∠2+∠3 ... Both sums are 180 degrees.
Statement 8: ∠1+∠4=∠4+∠3 .. ∠2 and ∠4 are equal (alternate angles)
Statement 9: ∠1= ∠3 , because ∠4 is common on both sides.
Statement 10: ∠1 = ∠3 .. hence, proved
