Question

In the below fig, `∠`1 = 60° and  `∠`2 = `(2/3)^(rd)`of a right angle. Prove that l || m.

Answer 1

Given:

`∠` = 60°, `∠`= `(2/3)^(rd)` to right angle

To prove: parallel to m

Proof `∠`1 = 60°

`∠`2 =` 2/3` × 90° = 60°

Since, `∠`1 = `∠`2 = 60°

∴ Parallel to m as pair of corresponding angles are equal
