Question

n above figure,

angle x = 103o, angle y = 72o,

Are lines m and n parallel ? Justify

Answer 1

• Sum of pair of interior angles same side of the transversal are supplementary then the lines are parallel.
• According to the problem given,x and y are pair of interior angles same side of the transversal.
• ∠x+∠y=71∘+108∘=180∘
• ∴,m and n are parallel lines.
