Chap 8 Vectors IV

Skew lines are...

• parallel and do not intersect

• parallel and intersect

• not parallel but they intersect

• not parallel and do not intersect

To find the point of intersection between two lines, we can...

• check if the direction vectors of both lines are a scalar multiple of each other

• equate the equations of the two lines

• find cross product of the two direction vectors

Select all options that are correct. To show that a plane contains a line, we need to show 2 things:

• line is parallel to plane

• line is not parallel to plane

• point on line is also on plane

• point on line is not on plane

To find the line of intersection of two planes, we can solve the _________ equations of the planes simultaneously using GC.

Select all options that are correct. To find the perpendicular distance from point A to the plane, we can find...

• 1

• 2

• 3

• 5

To find angle between a line and a plane, which of the following formulas can we use?
