Either perpendicular lines if the lines create 90o angles or intersecting lines.
Non-perpendicular intersecting lines. There is no special name.
Perpendicular lines
two lines that cross
Non interesting lines are called lines
If they are straight lines, then they define a plane in which both lines lie.
Think you just answered your own question. A plane is a line. Two planes= two lines.
Two lines in two intersecting planes can be parallel, intersecting, or skew.
Intersecting planes!
One.
Not really. A railroad intersection would be an example of two lines intersecting. An example of two planes intersecting would be the ground and the side of a building or the ground and the railroad crossing sign post.
Two intersecting straight lines uniquely define one single plane.
Yes as long as the two lines are intersecting at that point. For example if you looked at an x-y axis, the point (0,0) would lie on both the x and y axis or two different lines.
draw two intersecting lines that are not perpendicular
yes
C.intersecting lines
Intersecting lines are two lines that cross in a coordinate plane. So, yes, intersecting lines cross.
