Why is the right angle symbol not shaded in geometric artboards

In learning the ' Vertical relationship determination ' section of geometry, it is often necessary to identify the vertical relationship with a right-angled symbol to make it easier for everyone to identify. So the geometrical drawing board as an indispensable teaching aid tool, often used to do mathematical courseware, geometric artboards can also be quickly to match the vertical relationship of the object to mark the right angle symbol, but the system is set by the square symbol is shaded fill, how can we remove the shadow it? Let's make a small part to give you the right angle symbol in the geometric drawing board why not with a shadow.

As shown, if we draw a line segment in the geometry artboard, find the midpoint of the segment, and cross-point the vertical line of the segment. Select the Marker tool under the left-hand toolbox, hover over the midpoint and drag the mouse along the 45-degree azimuth to automatically mark the vertical right-angled symbol.

 
example of a vertical symbol in a geometry artboardClear right-angled glyph shadow operations are as follows:

Step one we select the "Move Arrow" tool in the left-hand toolbox of the geometry artboard, the mouse selects the right-angled symbol, and, in the Popup tab option, select "Properties", as shown;

Step two this pops up the Properties dialog box, we select the "Transparency" tab, use the mouse to move the slide button to the far left, and then click the "OK" button, as shown in the action;

 
Drag the transparency pointer to the leftmost example

Step three following the steps above, you will find that the inner shadow of the right-angle symbol disappears, so that the requirement is reached, as shown in the results.

The above is the geometric artboard in the right angle symbol why not with a shadow of the introduction, after the above operation, you can remove the shadow inside the right angle symbol. Geometric artboards also have a lot of detailed features, if you do not use, it is impossible to find, so it is recommended that you often use the geometry of the artboard, a lot of groping inside the function, so that in the drawing is to feel dazed.
