Shikha is rowing a boat due north-east. In which direction will she be rowing if she turns it through:
`(i)` a straight angle
`(ii)` a complete angle

Options

A. `(i)` North-West

`(ii)` South-East
B. `(i)` South-West

`(ii)` North-East
C. `(i)` South

`(ii)` North-East
D. None of these

Explanation

To solve the problem, we will analyze Shikha's rowing direction and the angles she turns.

### Step-by-Step Solution:

1. **Identify the Initial Direction:**
Shikha is initially rowing her boat due North-East (NE).

2. **Understanding Angles:**
- A **straight angle** is 180 degrees.
- A **complete angle** is 360 degrees.

3. **First Part: Turning through a Straight Angle (180 degrees):**
- If Shikha turns through a straight angle from North-East, she will turn 180 degrees.
- To visualize this, if she is facing North-East and turns 180 degrees, she will end up facing South-West (SW).
- **Conclusion for Part (i):** After turning a straight angle, Shikha will be rowing in the South-West direction.

4. **Second Part: Turning through a Complete Angle (360 degrees):**
- If Shikha turns through a complete angle from North-East, she will turn 360 degrees.
- A complete angle means she makes a full rotation and ends up facing the same direction she started.
- **Conclusion for Part (ii):** After turning a complete angle, Shikha will still be rowing in the North-East direction.

### Final Answers:
- (i) After turning a straight angle, Shikha will be rowing in the South-West direction.
- (ii) After turning a complete angle, Shikha will still be rowing in the North-East direction.
