Discussion Overview

The discussion revolves around finding the coordinates of the third point of a scalene non-right triangle given the lengths of all three sides and the coordinates of two points. It also touches on a related problem of finding points at a specific distance from a given point.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant asks how to find the coordinates of the third point of a scalene non-right triangle when the lengths of all sides and two points are known.
  • Another participant suggests simplifying the problem to finding all points at a distance d from a point X.
  • A later reply confirms that the problem involves finding the intersection of two circles based on the distances from the known points.
  • Further clarification is provided that the intersection of two circles requires the equations of both circles and involves solving for the common points.

Areas of Agreement / Disagreement

Participants appear to be exploring different approaches to the problem, with no consensus on a single method or solution yet established.

Contextual Notes

The discussion does not resolve the mathematical steps required to find the intersection of the circles or the specific method to derive the third point of the triangle.

If I know the length of all three sides of a triangle and the coordinates of two of those points, how can I find the coordinates of the third point (in a scalene non-right triangle)?

Thanks

If this problem is too hard, then let's try something easier.

If you have a point X, and you have a length d, can you find all points whose distance from X is d?
 
Yes, so I have to find the intersection of two circles. How is this achieved?
 
"intersection of two circles", means you have the equation (implied by the problem description) of each circle and you want to know what point they have in common. Two equations and two unknowns.
