Create a Basic Angle
 

Here are the steps to make a very basic angle.








 

 

 

 

Open the figure editor so you can start creating a new figure.
Right click anywhere on the Composer Screen.
Point to Insert
Click on Figure














A new window with the figure editor opens.

 

Create and attach two lines to form an angle.
In the figure editor, Click on the line button on the figure editor toolbar and a line will appear.



We need two lines, so Click on the line button a second time on the figure editor toolbar and another line will appear.

NOTE: Every time you click on a button on the toolbar to add a line, point, circle, arc, or arrow, the item is added to the figure box in the same spot in the upper left hand corner. So even though you just clicked twice on the line button to add two lines it only looks like there is one, because they are currently right on top of each other.
Now we will arrange the lines to form an angle.

First click and drag the top line to somewhere
else in the figure editor so we can see both lines.

Click and Drag the Points of one of the lines until it is in the position you want.

Click and Drag one Point of the second line over a point of the first line until you see a blue highlighted circle appear. Then release the point and the two endpoints will be attached.

Click and Drag the final Point of the second line until you have the angle you want.

Now, Click on any blank area of the Figure Editor to deselect everything. Now we need to select the points of our angle. To do this, hold down the CTRL key while clicking on the three points that will define our angle. (Make sure you click on them in order with the vertex being the second point selected).



All three points should be highlighted.

Click on the Angle button in the Figure Editor toolbar to create the angle.

Add arrows to your angle

Click on the Arrow button in the Figure Editor toolbar and an arrow will appear.


Click and Drag the arrow over one of the endpoints until you see a blue highlighted circle appear. Then release the arrow it will attach to the point.

Repeat the process to add an arrow to the other endpoint.

Note: Sometimes the arrow merges in the opposite direction you want. When this happens, click on the arrow to select it. Then Right Click the arrow and choose Reverse Direction.

Make the vertex point Invisible.
Select the vertex by clicking on it to highlight it. Right Click on the point and Select Visible.
The point will disappear.
 

 

Now you have an angle. Click on the in the top right hand corner of the Figure Editor box to close the editor and your angle will appear on the composer screen.




Now feel free to click and drag your number line anywhere on the page you need it.
