Angle constraint
================
-Angle constraint fixes angle between two lines.
+Angle constraint fixes the angle between two lines.
-| Angle between two lines is thought of as an angle between two vectors.
-| So each line is treated as a vector with starting point equal to the line start point
-and terminal point equal to the line end point.
+| Angle between two lines is seen as an angle between two vectors.
+| Each line is treated as a vector with start and end points equal to those of the line.

Input fields:
-- **Line 1** is the first line selected in the view
-- **Line 2** is the second line selected in the view
-- **Value** is an angle between the lines, could be modified to set the desirable value
-- **Angle type** is a type of angle measurement
+- **Line 1** is the first line selected in the view;
+- **Line 2** is the second line selected in the view;
+- **Value** is an angle between the lines, can be modified to set the desirable value;
+- **Angle type** is a type of angle measurement:
.. image:: images/angle_direct.png
:align: left
- **Direct** is an angle type measured directly between two lines.
+ **Direct** is the least angle between two lines;
.. image:: images/angle_complementary.png
:align: left
- **Complementary** zzzzzzzz.
+ **Complementary** is 180°- Direct angle between two lines;
.. image:: images/angle_backward.png
:align: left
- **Backward** zzzzzzzz.
-- **Text location** is a position of the angle value label relating to angle line (in the view)
+ **Backward** is 360°- Direct angle between two lines.
+- **Text location** is the position of the angle value label relatively to the angle line (in the view):
.. image:: images/location_left.png
:align: left
- **Left** inserts text at the left of the angle line.
+ **Left** inserts text to the left of the angle line;
.. image:: images/location_automatic.png
:align: left
- **Automatic** inserts text at the middle of the angle line if it has enough length, otherwise - to the left.
+ **Automatic** inserts text it the middle of the angle line if it has enough length, otherwise - to the left;
.. image:: images/location_right.png
:align: left
**Right** inserts text to the right of the angle line.
-When both lines are selected angle value is displayed in the property panel and in the view.
+When both lines are selected, the angle value is displayed in the property panel and in the view.
When creating the constraint, after selection of two lines at the first time:
-- drag the angle presentation in the view to the desired position (by move mouse and click once)
+- drag the angle presentation in the view to the desired position and click once;
- set desirable angle value in the input field in the view and press **Enter** or just press **Enter** to keep the current angle
