Question

Fill in the blanks so as to make the following statements true:
(i) If one angle of a linear pair is acute, then its other angle will be ………..
(ii) A ray stands on a line, then the sum of the two adjacent angles so formed is …………
(iii) If the sum of two adjacent angles is 180°, then the ………….arms of the two angles are opposites rays.

Answer 1

Answer:

(I) Obtuse

(ii)180°

(iii) opposite/non-common

Step-by-step explanation:

Fill in the blanks so as to make the following statements true:

(i) If one angle of a linear pair is acute, then its other angle will be obtuse.

Explanation: we know that linear pair form 180°,if one is acute (let 80°),then other will obtuse(100°)

(ii) A ray stands on a line, then the sum of the two adjacent angles so formed is 180°.

Explanation: On a straight line sum of all angles are 180°

(iii) If the sum of two adjacent angles is 180°, then the opposite/non-common arms of the two angles are opposites rays.

Explanation: Common arm of both angles can't be opposite ray.

So,opposite arms or we can say non-common arms of the two angles are opposites rays.
