Rube Goldberg Machine

This fun project covers all constructions that involve tangential arcs and lines.

To complete this project, you need to follow through the following steps:

1. Construct a tangent from point O to circle center A;
2. Construct a tangent touching internally between two circles of same diameter; B and C;
3. Construct a tangent touching externally between two circles of same diameter; D and E;
4. Construct a tangent touching internally between two circles of different diameter; F and G;
5. Construct a tangent touching externally between two circles of different diameter; H and I.
