In a pair of adjacent angles: (i) Vertex is always common, (ii) one arm is always common and (iii) uncommon arms are always opposite rays. Then
- A(ii) is false.
- B(iii) is false
- CAll (i), (ii) and (iii) are true.
- D(i) is false, but (ii) and (iii) are true.
Solution & Step-by-step Explanation
By definition, two angles are adjacent if they have a common vertex, a common arm, and their uncommon arms lie on opposite sides of the common arm. Statement (iii) claims the uncommon arms are always opposite rays—this specific condition is only true for a linear pair of angles, not all general adjacent angles. Therefore, statement (iii) is false.
