Question

If two rays lie directly opposite to each other with a ray standing on it ,then the adjacent angles so formed are called what ?​

Answer 1

Answer:

Two adjacent angles form a linear pair of angles if their non-common arms are two opposite rays, i.e., the sum of two adjacent angles is 180°. Vertically opposite angles: When two lines intersect, then the angles having their arms in the opposite direction are called vertically opposite angles.
