To sketch the situation described, follow these steps:
1. **Draw Triangle GHI**:
- Start by drawing triangle \( \triangle GHI \). Label the vertices \( G \), \( H \), and \( I \).
2. **Label the Points**:
- Select point \( J \) on line segment \( GI \) such that it is between \( G \) and \( I \).
- Select point \( K \) on line segment \( HI \) such that it is between \( H \) and \( I \).
3. **Draw Line JK**:
- Connect points \( J \) and \( K \) with a straight line. This line should cross through the interior of \( \triangle GHI \).
4. **Proportional Division**:
- To illustrate the condition \( \frac{GJ}{JI} = \frac{HK}{KI} \), you may label or mark segments:
- Measure the lengths of \( GJ \) and \( JI \), and adjust their lengths so that the ratio of these lengths equals the ratio of \( HK \) to \( KI \).
For example, if \( GJ \) is 2 units and \( JI \) is 4 units, then \( HK \) could be 1 unit and \( KI \) could be 2 units. This setup indicates that the division of the triangle by line segment \( JK \) is proportional, satisfying the given relationship.
### Conclusion
By sketching \( \triangle GHI \), marking points \( J \) and \( K \) appropriately on the segments \( GI \) and \( HI \) respectively, and ensuring that the line \( JK \) divides the triangle proportionally, you visually represent the concept in geometry of the triangle's proportional division.
Feel free to label the points, segments, and indicate the ratios on your sketch for clarity.
