Intersection of two perpendicular planes
Data for the task:
It is necessary to take from the article: Distance from a point to a plane.
- Through a straight line DE, draw a plane perpendicular to the plane of the triangle ABC.
Construct a line of intersection of two planes.
Determine the visibility of planes.
The solution of problems on descriptive geometry I produce in the automated design system AutoCAD and AutoCAD 3D. This training will allow you to develop spatial thinking and consolidate the possession of AutoCAD.
The problem of intersection of two perpendicular planes is completely based on the principles of solving the problem. The distance from a point to a plane is a perpendicular to the plane. We have already constructed a perpendicular to the plane DK and determined the intersection point of the perpendicular with the plane point K, also determined the visibility of the perpendicular DK relative to the plane of the triangle ABC.
Half of the 3 tasks for the intersection of planes we have already completed. It remains to construct the line of intersection of planes and determine the visibility of the planes.
