Question

which of the following pair of adjacent angle will make a linear pair. 1.89°,91°.​

Answer 1

Answer:

1 ) 89° and 91°

Step-by-step explanation:

Linear pair means 180°

hence 1 ) 89° and 91° makes a linear pair( 89° + 91° = 180°)

Answer 2

89° and 91° will make a linear pair.

Given:

89° and 91°

To find:

Check if given pair of angles can make a linear pair.  

Solution:

Let's know about what is a linear pair.  

Linear pair of angles:

• When two pair of angles are adjacent to each other and are formed by two intersecting lines then two angles are said to be linear angles
• The pair of linear angles add up to form 180°.
• As we know the measure of a straight angle is 180°, so their noncommon sides will form a straight line.

Given pair of angles are 89° and 91°

If given angles are linear pair of angles the sum of the angles must be equals to 180°

⇒ Sum of the given angle = 89° + 91° = 180°    

Therefore,

we can say that 89° and 91° will make a linear pair
