# What is the angle between antiparallel vector?

## What is the angle between antiparallel vector?

Anti-parallel vectors are those parallel vectors that are opposite in direction. Angle between such two vector is 180°.

## How do you find the angle between parallel lines?

The angle between two lines, of which one of the line is y = mx + c and the other line is the x-axis, is θ = Tan-1m. The angle between two lines that are parallel to each other and having equal slopes (m1=m2 m 1 = m 2 ) is 0º.

What is a parallel angle?

In general, they are angles that are in relative positions and lying along the same side. 2. Two lines cut by a transversal line are parallel when the alternate interior angles are equal. Alternate interior angles are a pair of angles found in the inner side but are lying opposite each other.

What is the angle between I and J?

The angle is 90 degree.

### What is the angle between 2a and 4a?

It means they have different magnitude. But, they are along the direction of vector . Hence, both the vectors are collinear vectors . So, the angle between them is zero.

### How do you find the angle of a vector product?

Using the cross product to find the angle between two vectors in R3. Let u=⟨1,−2,3⟩andv=⟨−4,5,6⟩. Find the angle between u and v, first by using the dot product and then using the cross product. I used the formula: U⋅V=||u||||v||cosΔ and got 83∘ from the dot product.

What are parallel angles?

Are supplementary angles 180 degrees?

Two angles are called supplementary when their measures add up to 180 degrees.

## Which angles are corresponding angles with angle 8?

Angle 8 and angle 16 are corresponding angles. If angle 8 is 16 degrees, what is the measure of angle 16? Two transversals cut a pair of parallel lines. Angle 13 and angle 15 are corresponding angles.

## What is the angle between the vectors A * B and B * A?

Answer: Anyway from this, we know that the A×B vector and B×A vector are equal in magnitude but in opposite direction, i.e they are antiparallel, so the angle between them is 180° or π rads.

What is the angle between the vectors î and Ĵ?

The angle between the two vectors (î + ĵ) and (ĵ + k̂) is pi/3 radian.
