Measure the angles using a protractor and fill in the following table with the pairs of corresponding angles. 1st Pair 2nd Pair 3rd Pair 4th Pair ∠ 1 = _ _ _ ∠ 2 = _ _ _ ∠ 3 = _ _ _ _ ∠ 4 = _ _ _ _ ∠ 5 = _ _ _ _ ∠ 6 = _ _ _ _ ∠ 7 = _ _ _ _ ∠ 8 = _ _ _ _ _ Observe the figure, by checking corresponding angles, which lines are parallel?

Given figure is, Pair of corresponding angles are ∠ 1 and ∠ 5 ∠ 2 and ∠ 6 ∠ 3 and ∠ 7 ∠ 4 and ∠ 8 1st Pair 2nd Pair 3rd Pair 4th Pair ∠ 1 = 105 ° ∠ 2 = ∠ 85 ° ∠ 3 = 105 ° ∠ 4 = 85 ° ∠ 5 = 105 ° ∠ 6 = 85 ° ∠ 7 = 105 ° ∠ 8 = 85 ° From the above table, we can observe that, each pair of corresponding angles are equal. We know that, if corresponding angles are equal, then the given lines are parallel to each other. So, given lines l and m are parallel and n is transversal.
