Tangent

Circle-Circle

Identify two circles on which you want the common tangent to be placed. Four solutions are made available in cyclical order.

Angle-Circle-Length

You use this function to specify the direction of the tangent below an angle with the positive x-axis.

1. First enter the angle and then select the circle or circular arc for the tangent.
2. Now specify the length of the tangent.

The tangent is drawn with the specified length in both directions at the tangent point of the circle. If you activate the right mouse button instead of entering the length, you can specify the length of the tangent graphically in one direction.

Point-Circle

You use this function to draw the tangent to the circle, starting from a point.

1. Specify the start point for the tangent.
2. Select the circle or the ellipse.

Of the two options available, that tangent is selected that is closest to the identification point. If the start point of the tangent is located on a circle, you will be asked to enter the length of the tangent. The tangent is placed on the tangent point in two symmetrical partial lines.
