Question

Which angles form a linear pair? 1 and 3
2 and 3
2 and 5
1 and 4

Answer 1

2 and 5

Explanation:

A linear pair angles are angles on a straight line, whose sum equals to 180°.

Examining the diagram given, angle 2 and angle 5 are on a straight line. Thus, they are a linear pair. Their sum would equal 180°.

Form the options given, the angles that would form a linear pair are:

Angles 2 and 5.
