Two angles forming a linear pair are always _____.

Open in App

Solution

Linear pair:
Linear Pair: A linear pair is a pair of adjacent angles formed when two lines intersects.
Let $AB$ and $CD$ be two intersecting lines.
So, $∠ ACD$ and $∠ BCD$ are linear pairs.
Thus, $∠ ACD + ∠ BCD = 180 °$
Hence, two angles forming a linear pair are always supplementary.
