Mathematics

A ray stands on a line, then the sum of the two adjacent angles so formed is ______.

$180^o$

SOLUTION

If a ray stands on a line, then the sum of two adjacent angles so formed is 180.Conversely if the sum of two adjacent angles is 180, then a ray stands on a line (i.e., the non-common arms form a line).
