# Add a Line with a Fixed Angle

This mode allows a line to be constructed with a fixed numerically given angle to another line. The new line and a point through which it should pass can be added with a press–drag–release sequence. The point through which the new line should pass can also be generated with this mode.

When you select this mode, the property inspector pops up, asking you to specify the desired angle.

Otherwise, the use of this mode is analogous to add a parallel mode.

- Move the mouse over the line to which you want the new line to make an angle. Press the left mouse button. The new line and the point through which it should pass are created.
- Hold the left button and drag the mouse. You can move the new line and the new point to the desired position.
- Release the mouse button. Now the construction is frozen. The definition of the new point is adapted according to the position at which you release the mouse button.

#### Synopsis

This mode creates a line with fixed angle with respect to another line with a press–drag–release sequence.

#### Caution

The definition of angle depends on the chosen geometry.
