What is a geometric sketchpad? Question 1: What is the geometric sketchpad? Geometer's Sketchpad is a mathematical graphics software developed by an American company. In China, 1996 made extensive use of teaching AIDS in middle schools at the request of the then State Education Commission. Its function plays an important role in physics geometry, solid geometry, trigonometric function, analytic geometry and mechanical analysis. If you learn how to use this software, math and physics will be of great help. If you are a junior high school student, it shows that the school has a strong awareness of teaching reform and students have learned the weapon of active learning. If it's high school, learn as soon as possible. The practical examples of many courses in high school math books are geometric sketchpads. If you are a college student, congratulations, you will have new skills as soon as you join the work.
Question 2: What are the icons on the Geometer's Sketchpad? A compass.
Question 3: What is the core of the Geometer's Sketchpad? Geometric sketchpad is a general teaching environment for mathematics and physics. The function of geometry sketchpad specialty enables users to customize the required teaching courseware. The geometry sketchpad suitable for geometry teaching software provides an environment for observing the internal relations of geometry and exploring the mysteries of geometry. At present, the latest version of the Geometer's Sketchpad is downloaded from the Geometer's Sketchpad Chinese website, where I also downloaded it. I suggest you download it and try it. I hope it can help you.
Question 4: Who made the geometric sketchpad (founder)? Geometer's Sketchpad is an excellent educational software produced and published by KeyCurriculumPress Company in the United States. 1996, the company authorized People's Education Publishing House to distribute the Chinese version of the software in China. Just like its name is "2 1 century dynamic geometry", it can dynamically show the position relationship and operation change law of geometric objects, and it is the "sword" for mathematical physics teachers to make courseware!
Question 5: Is there an APP similar to Geometric Sketchpad on Android phone? What is this? Generally speaking, software such as geometric drawing is not supported, and the software package is too large and complicated to drive. It works well on the computer. Geometric sketchpad has two systems, windows and Mac, which can meet all requirements. It seems that the Geometry Sketchpad has detailed tutorials and courseware templates, which can be downloaded.
Question 6: Which of the following are not new features of Geometer's Sketchpad 5.0? The functions of the geometric sketchpad are mainly embodied in the following aspects: (provided by official website)
A tool for drawing straight lines and circles
Geometric sketchpad is more accurate than general drawing software when drawing graphics, and it meets the strict requirements of mathematics. Lines can be divided into line segments, rays and straight lines; A circle is a perfect circle. It can be used to complete all ruler drawing and deduce Euclidean geometry. To draw common figures such as parallel lines and vertical lines, you can open the "Construction" menu and directly click the required figure.
Two graphic changes
Through the toolbox in the Geometry Sketchpad, the original graphics can be rotated, translated and scaled at will according to the specified value, calculated value or dynamic value, and the geometric relationship remains unchanged during its change, which is more helpful to study the movement and transformation of graphics.
3. Measurement and calculation functions
Geometric sketchpad can measure the length of line segments, angles of various angles and so on. , and calculate the measured values, including four operations, power function, trigonometric function, etc.
Draw various function images
Under the coordinate system function of Chinese version, users can draw various complex function images. The function curve can be understood more deeply through the change of parameters.
Verb (abbreviation for verb) Many functions in Windows applications.
The geometric sketchpad can select the font and font size for the text; Add color to the graphics; Use the clipboard to exchange information with other programs in Windows, such as adding pictures and sounds to the geometric sketchpad, or inserting the drawn graphics into the math test paper edited by WORD.
Make complex animations
Although it can't be made directly, the geometric sketchpad can define, construct and transform simple animation and motion to get the required complex motion. Using the convenient trajectory tracking function, we can clearly understand the motion trajectory of the target.
The scripts
Geometric sketchpad can record the drawing process of geometric figures at any time, with recovery and recovery browsing. Moreover, the script can also record the whole drawing process in language.
Maintain and highlight the geometric relationship.
Maintaining geometric relations is the essence of geometric sketchpad. No matter how the geometric figures in the sketchpad change, the geometric relationship between them is unchanged. This is precisely the essence of geometry, that is, to study the unchanging geometric laws in the ever-changing geometric figures.
Question 7: What is the speed unit of the geometric sketchpad in centimeters per second? In "Edit → (Hold down shift) Advanced Parameter Options → System".
How to use the powerful geometric drawing software-Geometric Sketchpad? If you want to use this software, you need to be very familiar with its interface. For example, its menu bar is powerful and flexible, and you can create, save and print files, as well as modify, format and customize the objects in the artboard.
The menu bar mainly includes: file menu, edit and display menu, construction and transformation menu, measurement and data menu, drawing menu, window menu and help menu.
Example of geometric sketchpad menu bar
Detailed geometric sketchpad menu bar:
1. File menu: You can create, save and print the whole document.
2. Edit Menu and Display Menu: Contains commands to change the appearance and format and define the current artboard object.
3. Menu of construction, transformation, measurement, data and drawing: support defining new mathematical contents on the current drawing board and creating new objects related to the selected objects.
4. Window menu: used to manage document windows opened on the desktop.
5. Help menu: provide a series of help, such as geometry sketchpad learning center, reference center, online resource center, etc.
6. Context menu: Right-click on the artboard (Windows version) or Ctrl+ click (Mac version) to display the options related to clicking the object, or if you click in the blank area, the options related to the artboard document will be displayed.
The above is the menu bar of the Geometry Sketchpad. When you are familiar with these menus, you can skillfully use them to draw geometric figures. At present, the software is engaged in double eleven activities, which need to be done quickly.
