Question

How do you identify vertical angles?

Answer 1

Hint: To solve this type of question we should definitely know what are vertical angles exactly. Are they vertically placed or anything like that? Then we will take an example also to get more clarity. It is just a type of pair of angles.

Complete step by step solution:
We know that in geometry. There are pairs of angles called and known by different names and different properties like opposite angles, corresponding angles, angles in linear pair, alternate angles, adjacent angles. So each type has its own properties and identifications.
In the case of the above mentioned type, this is formed when two lines or rays intersect each other the way we have drawn below.

This is the simplest way to show the vertical angles. Note to identify the angles we have some points like
1. This is a pair that is opposite to each other.
2. They are equal in measure.

Note: Note that each type or pair has its own property. So identifying them is simple. Like corresponding angles are observed where two lines are parallel. There is no such restriction on vertically opposite angles. Angles in linear pairs together add to make \[{180^ \circ }\]. But no such restriction on vertically opposite angles. So note these things.
