Question

# Two lines that are not perpendicular intersect such that ∠1 and ∠2 are a linear pair, ∠1 and ∠4 are a linear pair, and ∠1 and ∠3 are vertical angles. Tell whether the following statement is true or false.

- True
- False

Hint:

### When the lines are perpendicular then angles are equal.

## The correct answer is 'False'.

### ∠1 and ∠2 are a linear pair, so they are supplementary, not congruent.

Hence, the statement is false.

Here, sum of angles 1 and 2 is 180°.
