2nd ESO. UNIT 7.8 Basic tangents and transitions

When you draw plane geometric shapes, you need to bear in mind a number of considerations regarding transitions and tangents.

A transition is the harmonic connection of TWO LINES, A LINE AND AN ARC or TWO ARCS that ensures their succession or continuity to make a continuous line.

A line and a circumference or two circunferences are tangential when they have only ONE POINT in common.
