Homework Help Overview

The discussion revolves around proving geometric relationships involving circles and tangents, specifically focusing on the points where lines AD and BD touch the circle at points A and B. The original poster presents two statements to prove regarding the segments DF, AF, and EF.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to prove relationships between segments but expresses difficulty in establishing that DF equals FB. Other participants inquire about the visibility of the relevant image, suggesting alternative methods for assistance.

Discussion Status

The discussion appears to have shifted as the original poster later indicates they managed to solve the problem independently. However, prior to this, there was a lack of consensus or resolution among participants regarding the initial proof attempts.

Contextual Notes

There is mention of an image that is pending approval, which may contain critical information for the problem. The original poster also acknowledges an earlier mistake in uploading the correct image.

AD and BD touch the circule at points A and B
AC is parallel to BD
prove that:

1. DF^2 = AF*EF
2. BF = DF

its obvious that BF^2 = EF * AF i tried proving that DF = FB but with no luck.

edit: i uploaded the wrong picture earlier, terribly sorry i have so many of them :smile:

anyone? :rolleyes:
 
I cannot see the image so I cannot help you out. If you are still stuck a faster way may be to send the image in an email and I could help you out then.
 
The attachment if you see is yet to be approved ...
