Answer:
Options (3) and (4)
Step-by-step explanation:
When two lines intersect each other at a point, angles formed on the point are called as linear pair.
Since pair of linear angles is supplementary, sum of linear angles will be 180°.
m∠1 + m∠2 = 180°
Therefore, both angles 1 and 2 are linear and supplementary.
Options (3) and (4) are the correct options.
