Teach you how to measure a linear equation with geometric artboards

When drawing graphics with geometric artboards, we often use equation expressions to draw function images, and in fact we can use geometric artboards to get an expression of images. Taking straight lines as an example, here is how the linear equation of the geometrical artboards is obtained.

The following are the steps:

Select "Draw"--"define coordinate system" to hide the grid. Use the Point tool and line segment tool to draw an arbitrary triangle ABC in the drawing area.

　　

Select the point A and segment BC, click on the "construct"--"Vertical" menu command, draw the line segment BC perpendicular, perpendicular to D. Select perpendicular, press "crtl+h" to hide the vertical line, and use the Segment tool to construct the segment ad. The same method constructs line ab for high CE.

　　

The intersection between AD and CE of the segment is H. Select the point h, select "Measure"--"horizontal axis" to measure the horizontal axis of H point, the same method measures the ordinate of H point.

　　

Select point B and Line AC, click "Construct"--"Vertical" menu command, draw out the line of AC over point B, perpendicular is f. Select the line bf, select "Measure"--"equation", the plot area shows the equation of the straight BF.

　　

Note: After the equation expression is out, the point can also be verified, the H-point of the horizontal axis into the equation to calculate the ordinate will find that the calculated value is consistent with the measure.

The above content introduces the measurement method of the linear equation of the geometrical drawing board, and obtains the function expression through the image.
