Answer: intersecting but not perpendicular

Step-by-step explanation: Let's start by eliminating a few options.

First off, parallel lines are coplanar lines that do not intersect.

In the diagram shown, lines i and k do intersect

so option A doesn't make any sense.

We can also eliminate option C because by definition,

parallel lines do not intersect so we can cross this off.

We also can't conclude that lines i and k are perpendicular,

because we don't have a box at the vertex and from the

diagram shown, it doesn't look like they form a perfect right angle.

That leaves us with option D.

Notice that these two lines cross at a point.

When two lines cross at a point, we say that they intersect.

So they are intersecting lines but not perpendicular.
