Match List-I with List-II.
| List-I | List-II | ||
|---|---|---|---|
| (A) | Reflex angle | (I) | Two angles whose sum is 180° |
| (B) | Linear pair of angles | (II) | Greater than 180° but less than 360° |
| (C) | Supplementary angles | (III) | Two angles whose sum is 90° |
| (D) | Complementary angles | (IV) | Two adjacent angles whose sum is 180° |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-II, B-IV, C-I, D-III
(A) Reflex angle — this matches (II) Greater than 180° but less than 360°. A reflex angle is larger than a straight angle but less than a full turn.
(B) Linear pair of angles — this matches (IV) Two adjacent angles whose sum is 180°. A linear pair shares a vertex and an arm, and its other two arms form a straight line, so the angles are adjacent as well as adding up to 180°.
(C) Supplementary angles — this matches (I) Two angles whose sum is 180°. They need not be adjacent; only their sum matters.
(D) Complementary angles — this matches (III) Two angles whose sum is 90°.
