SUMMARY

The discussion focuses on solving a geometry problem involving a triangle with side lengths in a 3:4:5 ratio and the tangents from its angles to the inscribed circle. The problem requires finding the ratio p:q, where p is the length from the ray of the greatest angle to the tangential point, and q is the length from the intersection of the two rays to vertex C. The solution involves using mass point geometry and understanding the properties of tangents and bisectors in triangles.

PREREQUISITES

Homework Statement


In triangle ABC, there is a maximun circle (3 intersection points) such that the lengths of the triangles are 3 : 4 : 5. A ray from the smallest angle C is tangential to the opposite side. Another ray from the greatest angle B is also tangential to the opposite side.

Find p : q where p is the length between the ray from the greatest angle to the tangential point and the intersection of this ray to another ray from smaller angle;
q is the length between the intersection of two rays and the vertex C.


The Attempt at a Solution



The problem can be solved by Mass point geometry and areas/lengths.
However, I am not sure about the ratios of how the rays divide triangle's two sides.

We do know that whether the rays are bisectors although they meet inside the circle.

How would you solve the problem?

I don't follow your description of the problem. Is there a picture you can upload? I don't know where the extra triangles are, unless that was a typo in the first line.

The problem in the original form:

A circle inscribed in a 3-4-5 triangle. A segment is drawn from the smaller acute angle to the point of tangency on the opposite side. This segment is divided in the ratio p : q by the segment drawn from the larger acute angle to the point of tangency on its opposite side. If p > q then find p : q.

The same problem is in the following picture at

You can see a triangle which shows you how I understand the question.
