# The intersection of two planes of the triangles ABC and EDK

We have already carried out the problem on the intersection of planes, and also determined the visibility of the planes.

In this video lesson on descriptive geometry, we perform the task of intersection of two planes defined by triangles ABC and EDK, i.e. fix the material you have covered.

After we construct the line of intersection of the planes given by the triangles, we define the visibility of the planes by the method of competing points.

Given:

NOTE

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.
