# Can two angles be supplementary if both of them are: (i) acute (ii) obtuse (iii) right?

##### SOLUTION
(i) No, because sum of two acute angles is less than $180^o$.
(ii) No, because sum of two obtuse angles is more than $180^o$,
(iii) Yes, because sum of two right angles is $180^o$.

Q5 Subjective Medium
Read the following two statements which are taken as axioms:
(i) If two lines intersect each other, then the vertically opposite angles are not equal.
(ii) If a ray stands on a line, then the sum of two adjacent angles so formed is equal to $180^0$.
Is this system of axioms consistent? Justify your answer.
