How to tell if the two vectors are parallel, orthogonal or neither

The video tutorial explains the concepts of vectors, focusing on parallel and perpendicular vectors. It discusses how to determine if vectors are parallel by comparing slopes and explains that perpendicular vectors have a dot product of zero, indicating orthogonality. The tutorial includes a step-by-step calculation of the dot product to demonstrate this concept.

What is the key factor in determining if two vectors are parallel?

• Their angles

• Their slopes

• Their magnitudes

• Their dot product

What angle is formed between two perpendicular vectors?

• 180 degrees

• 90 degrees

• 60 degrees

• 45 degrees

What is the dot product of two orthogonal vectors?

• Undefined

• -1

• 0

• 1

Which operation is used to determine if vectors are orthogonal?

• Subtraction

• Dot product

• Addition

• Cross product

In the example, what is the result of the dot product calculation?
