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:

### Vertical angles are formed when two lines meet each other at a point. They are always equal to each other. In other words, whenever two lines cross or intersect each other, 4 angles are formed. We can observe that two angles that are opposite to each other are equal and they are called vertical angles.

## The correct answer is 'True'.

### According to the congruent supplement theorem, ∠1 and ∠2 are supplementary angles, and ∠1 and ∠4 are supplementary angles, so ∠4 and ∠2 are congruent.

Hence, the correct option is A.

Vertical angles are always equal.
