The two angles which form a linear pair are always supplementary.
Linear angles and supplementary angles
Linear angles are the two adjacent angles whose sum is equal to 180°
The sum of supplementary angles is also 180°.
Hence, the above statement is true.

(v) If two lines intersect at a point, then the vertically opposite angles are always _______.
(vi) If two lines intersect at a point, and if one pair of vertically opposite angles are acute angles, then the other pair of vertically opposite angles are _______.
Which of the following statements are true., (T) and which are false (F)?
(i) Angles forming a linear pair are supplementary. (ii) If two adjacent angles are equal, then each angle measures 90∘. (iii) Angles forming a linear pair can both be acute angles. (iv) If angles forming a linear pair are equal, then each of these angles is of measure 90∘.
