Question

5. Can two angles be supplementary tf both of them are:
(1) acute? (ii) obtuse?​

Answer 1

Answer:

Sum of two acute angles cannot make a supplementary angle. As we know that obtuse angle is always greater than 900. So, the sum of two obtuse angles always makes greater than 1800. ∴Sum of two obtuse angles cannot make a supplementary angle.

Answer 2

• ∴Sum of two acute angles cannot make a supplementary angle. As we know that obtuse angle is always greater than 900. ... So, the sum of two right angles is always equal to 1800.

• (of an angle) more than 90° and less than 180°.
