Geometry and Discrete Math Links

Click For Summary

Discussion Overview

The discussion revolves around seeking resources and explanations related to geometry and discrete mathematics, specifically focusing on the properties of circles and the behavior of tangents between intersecting circles.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant requests links summarizing the properties of circles in geometry and discrete math.
  • Another participant provides a link to MathWorld that is intended to help with the inquiry about circles.
  • A question is posed regarding the general rules for a tangent that touches two points on different-sized overlapping circles.
  • One participant mentions that a known rule is that the chord drawn from the intersection points of the circles bisects the common external tangent.
  • A follow-up question seeks clarification on whether extending the chord to meet the tangent results in the tangent being bisected.
  • A later reply confirms that the tangent will indeed be bisected if the two points of intersection are connected and extended.

Areas of Agreement / Disagreement

Participants generally agree on the rule regarding the bisecting of the tangent, but the initial request for resources remains unresolved as no comprehensive list of properties has been provided.

Contextual Notes

The discussion lacks specific definitions and detailed explanations of the properties of circles, as well as the broader context of discrete math in relation to the topic.

Would anyone happen to have some links which briefly explain some of the laws in geometry and/or discrete math? At the moment, i am looking for a summary of the Properties of Circles .

Thank you for being as helpful as you always are.

I found MathWorld, although i can not find properties of circles section. :confused: link

No one?

bump!
 
What are some general rules regarding a tangent which lies on two points; these two points are each on a different (sized circle), and the two circles are overlapping each other (intersecting at two points).
 
The only one I know of (though there may be more) is that the chord drawn from the two points of intersection of the circles bisects the common external tangent.

Hope that helps! :)
 
So if the two points of intersection are connected, and are extended to meet the common tangent, the tangent will be bisected?
 
Yes, that's correct.
