Question
Name a pair of angles that are vertical.
- Angles 4 and 5
- Angles 7 and 9
- Angles 8 and 9
- Angles 5 and 7
Hint:
Vertical angles are formed when two lines meet each other at a point.
The correct answer is: Angles 7 and 9
Angles 7 and 9 are vertical angles.
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.
