Geometry Problem 1148: The Enigmatic Connection: Exploring Right Triangles, Circles, and Tangents

< PREVIOUS PROBLEM  |  NEXT PROBLEM >

Given a right triangle ABC with the circumcircle O, the incircle O1 (with a radius of r1) and the circle O2 (with a radius of r2), which is tangent to AB, BC, and arc AC at points C2, A2, and B2, respectively, the objective is to prove that r2 = 2r1.


Right Triangle, Circle, Incircle, Circumcircle, Tangent, Radius

Inradius and right triangle's quest,
Circles and tangents put to the test.
Unveiling the connection profound,
Prove their harmony can be found.
