Detailed tutorial on drawing the vertical center of a triangle using geometric sketchpad

Want to draw the vertical center of a triangle, but there is no detailed tutorial? PHP editor Youzi has specially prepared a tutorial for drawing the vertical center of a triangle with a geometric sketchpad. This tutorial will guide you step-by-step from drawing a triangle to finding its orthocenter. If you are interested in perpendiculars of triangles, or need help with your math homework, continue reading the following detailed tutorials.

1. Draw △ABC.

Open the geometry sketchpad mathematics courseware production tool, use the line segment ruler tool, and first draw a triangle ABC.

2. Draw a vertical line with three sides.

When the mouse clicks on a vertex A and an opposite side BC of the triangle, the selected state will appear. Then click [Construction] - Vertical Line, so that the vertical line of one side will appear.

The same operation can be used to complete the vertical lines on other sides. Finally, the intersection of the three vertical lines at one point is the vertical center, which is recorded as point O.

Using the construct vertical line command, you can also draw many geometric figures, such as isosceles right triangles.

For the sake of beauty, you can perform the following operations:

3. Draw vertical points.

Select the point tool in the toolbox on the left and draw three vertical points D, E, and F on △ABC.

4. Hide the vertical line.

Select one of the vertical lines, right-click the mouse, and execute the Hide Vertical Line command or press the shortcut key [Ctrl H] to hide it. Then hide all three vertical lines.

5. Mark vertical relationships.

Click the line segment ruler tool to connect the vertices of the triangle and the perpendicular points of its opposite sides to make vertical segments. Use the marker tool to draw an angle on the vertical foot, which will then appear as a right angle. Mark all three vertical line segments, as shown in the final picture.
