TANGENCIAS: CIRCUNFERENCIAS TANGENTES A RECTA Y CIRCUNFERENCIA dado el radio. Geometría plana.

This content is part of the topic of tangencies taught in the first and second years of high school (Bachillerato) in the plane geometry unit and belongs to the "Tangencies and Connections" playlist. In this video, I explain how to solve basic tangency problems involving circles tangent to a line and to a circle, given the radius. I hope you find it useful!
