In Fig, ∠1 = 60° and ∠2 = \((\frac{2}{3})\)° if a right angle.

1.	In Fig, ∠1 = 60° and ∠2 = \((\frac{2}{3})\)° if a right angle. Prove that l \|\| m.
Answer» Given, ∠1 = 60° ∠2 = \(\frac{2}{3}\) of right angle To prove: l ‖ m Proof: ∠1 = 60° ∠2 = \(\frac{2}{3}\) x 90° = 60° Since, ∠1 = ∠2 = 60° Therefore l ‖ m as pair of corresponding angles are equal.

In Fig, ∠1 = 60° and ∠2 = \((\frac{2}{3})\)° if a right angle. Prove that l || m.

Answer»

Given,

∠1 = 60°

∠2 = \(\frac{2}{3}\) of right angle

To prove:

l ‖ m

Proof:

∠1 = 60°

∠2 = \(\frac{2}{3}\) x 90° = 60°

Since,

∠1 = ∠2 = 60°

Therefore

l ‖ m as pair of corresponding angles are equal.
