Detailed method of making hot text using Geometric Sketchpad

When using Geometry Sketchpad software, you want to add hot text to geometric figures to quickly view specific information, but don’t know how to do it? PHP editor Xigua brings you a detailed tutorial on making hot text with geometric sketchpad. The following will guide you step by step on how to add hot text to graphics, solve problems, and make the use of Geometric Sketchpad more efficient.

When the hot text is executed in the [inside] of the object, the essence of flickering is that the internal color and the background color mutually appear, so the [internal] color cannot be set to the same as the background color. If the background and the interior are the same color, only the border is flashing. If the white object must flash inside, please change the artboard background to non-white.

As shown in the picture above, there is a button for [Hide Point C], a measurement value measuring the distance between point B and point C, and ∠A and ∠C have been marked by the marking tool. When entering text, move the mouse close to these objects, and the mouse will change shape. Click on the object, and the object name will enter the text and be surrounded by a pink circle. When the mouse changes to the Move Arrow tool, slide over or hold down the hot text and its object will flash. Among them, the action of [hidden point C] will be executed. If you right-click a text line and select [Properties] - cancel [Can be selected], this text line cannot be selected. The hot word function will be more useful in dynamic presentations. It is very convenient to use hot text to present drawing board documents on the electronic whiteboard.

If there are parameters, measurements, or calculated values ​​in the drawing area, you can click the parameter or value to turn it into hot text and insert it into the text when editing text. The [Interior] of objects such as polygons, circles, and bows must be created first before their [Interior] can be introduced into hot text. If a corner has not been marked by a marking pen in advance, when editing text, you can left-click and slide from the corner vertex to the inside of the corner to [temporarily] mark the corner and introduce it as hot text. When clicking on an object, hold down the Shift key, and a menu will appear to select the form and content to be [heated]. [Label] is the system default name; [Symbol and Value] is to display the positive and negative signs of the number together with the number; [Name] is the name of the object display. Pictures drawn by the marker pen or pictures in the drawing area can also be imported as hot text. When you click to introduce content, the picture flashes.

If the points (line segments) that need to be introduced into the hot text overlap together, click on the label of the object to insert the hot text into the object, as shown in the picture on the right above. When a line segment is introduced, because the artboard constructs a directed line segment, there are short lines above the name letters of the line segment. If you want to introduce a line segment name without a horizontal line, you can modify the label of the line segment. At this time, the introduced line segment name is the label of the line segment. Then change the color of the label to the same color as the artboard background to [hide] the label. When the label of an object is obscured by many objects or interferes with the selection and is difficult to select, you can use the geometric sketchpad text tool to select the label and drag it to change its position.
