Always true.
Explanation of Solution
Given:
The given statement is:
Two
Calculation:
In supplementary angles, the sum of measures of two angles in 180.
A linear pair is the pair of adjacent angles with non-common sides that are opposite rays.
According to Angle-Pair relationship, the angles forming linear pairs are supplementary.
Here, angle 1 and angle 2 form a linear pair.
So,
Hence, the statement is always true.
