what are linear pair

 

 A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Anushree has copied the from http://www.geom.uiuc.edu/~dwiggins/conj02.html give thumbs down to her. If you dont belive me then visit this site and watch the explanation (the first para.) .

 the two adjacent angles which form 180 degerees 

if two adjacent angles which form 180 degreesit is called as linear pair

a straight line which measures 180 degrees is call linear pair.

i mean called linear pair
