Given rectangular prism abcd. choose all of the terms that best describe each of the sets of lines or points. lines ab and cd collinear intersecting parallel noncollinear coplanar

Two points are collinear when they lie on the same line. Points are collinear but not lines. Rather when two lines lie on the same plane we say they are coplanar.

Hence, line AB and CD are NOT collinear, so they are noncollinear and they are coplanar.

Two or more lines are said to be intersecting, when the lines meet at some point, when lines are not intersecting they are said to be parallel.

Recall that one of the properties of a rectangle is that opposite sides are parallel.
Notice that line AB and CB are the opposite sides of the rectangle ABCD.

Thus, line AB and CD are not intersecting but are parallel.

Therefore, the terms that best describe lines AB and CD are
parallel
noncollinear
coplanar

Yuh yeet honestly idk
