Question:
In the below fig, ∠1 = 60° and ∠2 = (2/3)rd of a right angle. Prove that l ∥ m.
Solution:
Given:
∠1 = 60° and ∠2 = (2/3)rd of a right angle
To Prove: Parallel Drawn to m
Proof ∠1 = 60
∠2 = (2/3) × 90 = 60
Since ∠1 = ∠1 = 60°
Therefore, Parallel to m as pair of corresponding angles are equal.
