Rectangle inscribed in Triangle

Click For Summary
SUMMARY

The discussion centers on finding the locus of intersection points of the diagonals of a rectangle inscribed in triangle ABC, where points P, Q, R, and S are located on sides AC, BC, and AB, respectively. The participants express difficulty in progressing with the problem, with one user attempting to apply complex numbers to interpret the geometric situation. The consensus is that the locus is likely not a line, contradicting initial assumptions, indicating a need for deeper geometric analysis.

PREREQUISITES
  • Understanding of basic geometric concepts, particularly triangles and rectangles.
  • Familiarity with locus of points in geometry.
  • Knowledge of complex numbers and their application in geometric problems.
  • Elementary skills in geometric proofs and constructions.
NEXT STEPS
  • Research the properties of loci in geometry, specifically in relation to inscribed figures.
  • Study the application of complex numbers in geometric interpretations.
  • Explore geometric proofs related to the intersection of diagonals in polygons.
  • Investigate advanced topics in Euclidean geometry that involve loci and inscribed shapes.
USEFUL FOR

Students and enthusiasts of geometry, particularly those interested in advanced geometric constructions and the application of complex numbers in geometric contexts.

Let PQRS be a rectangle inscribed in a triangle ABC(i.e P is in AC, Q in BC and R,S are in AB). Find the locus of points that are intersection of diagonals of the rectangle. (i.e find the locus of intersection of RQ and PS)

Sounds like a homework problem!

If you would care to post where you've gotten on the problem (even if your thoughts are seemingly trivial), then maybe we could help you work through the point where you're stuck.
 
Hi. Well, it's not a homework problem, that's for sure. I haven't done much progress on this problem, seems quite hard. Or perhaps just my elementary geometry skills suck ? I've tried to somehow interpret this geometric problem in complex numbers' language, you know, but didn't really work as I thought. First I thought the locus should be a line, but now I doubt it. I think it's not. I may be wrong. Thank you !
