## 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:

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