Question

question 2
which pairs of angles do not form a linear pair?
1 and 2
2 and 4
4 and 3
none of the angles form linear pairs.
question 3

Explanation:

Step1: Recall linear - pair definition

A linear pair of angles is a pair of adjacent angles whose non - common sides are opposite rays and whose sum is 180 degrees.

Step2: Analyze each option

• For angles 1 and 2: They are adjacent and their non - common sides are opposite rays, so they form a linear pair.
• For angles 2 and 4: They are not adjacent, so they do not form a linear pair.
• For angles 4 and 3: They are adjacent and their non - common sides are opposite rays, so they form a linear pair.

Answer:

2 and 4
