One of the angles forming a linear pair is a right angle. What can you say about its other angle?


SOLUTION
We know that, two angles are said to be linear pair of angles, if they are adjacent angles and their sum is $$180^o$$.
let the two angles be $$x$$ and $$y$$, which formed linear pair.
Given, one of the angles is right angle, i.e., $$90^o$$
=> $$ x  = 90^o$$ 
$$ x+ y = 180^o$$
$$ 90 + y = 180^o$$
$$ y = 90^o$$
$$\therefore $$ other angle is also a right angle.
