D. angle. When a line intersects a surface or another line it does so at a single point. I. But when two planes intersect, their intersection is a line (this is easy to see: imagine two intersecting pieces of paper). Two planes intersect. In the case of finding the line at which two planes intersect, you need to take the cross product of the normal of the two planes. In these case the two lines intersect at only one point. In the figure below, point (3,4) is the intersection of line x = 3 and line y = 4 since that is where the two lines cross. This angle is typically an acute angle, which is supplemented by an obtuse angle. Related Questions in Mathematics. When two distinct planesmeet, they intersect at a line. • Parallel planes have parallel normal vectors. Then since L is contained in P The 2 nd line passes though (0,3) and (10,7). I am so confused with this last part of the unit! The two planes intersect at a point. In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. b. Two points must be collinear. The lines are coplanar. If two coplanar lines do not intersect, hence they are parallel. For example, the spherical angle formed by two great circles on a sphere equals the dihedral angle between the planes containing the great circles. Understand the Problem In the diagram, you are given three lines, p, q, and r, that intersect at point B. I recently developed an interactive 3D planes app that demonstrates the concept of the solution of a system of 3 equations in 3 unknowns which is represented graphically as the intersection of 3 planes at a point..
