How can you get the angle between 2 objects?

Question

with X/Y coordiates.

First object say it has these X/Y coordiates ...

X: 100

Y: 200

Then the second has ...

X: 150

Y: 100

How would I determine the degree of angle between these two using maths?

Answer 1

Sorry, you can't determine an angle between two points.  You should go back to the problem, there must be other information.  Like, do you need to include the origin?  Also, refer to a coordinate pair as follows:

(x, y) so your points are (100,200) and (150,100)

Answer 2

the angle that meets of the two shapes measure it with a protractor.

the bottom line if it x so the top axes is y therefore draw a line graph or a bar graph plotting 100 and 150 at the bottom axes labeling the first as shape one and the second as shape two, then the top axes as 100 and 200. the line that meets between the two shapes is th degree of the angle which you measure. or draw a line of best fit. x

Answer 3

Depends what angle you re looking at the objects from

Answer 4

Draw the line on a graph.  Create a right angled triangle with that line, then use the sine, cosine or tangent thingy to work it out.  It's been a lot of years since I did that, so you'll have to use you knowledge as well.

Answer 5

my best guess would be add your 2 angles x and y

then subract that number from 360.

easy geometry

Answer 6

I presume you mean the angle between the lines joining the origin to these two points, as you can't have an angle between two points. You get the angle of each line by taking its tangent, and then subtract the two angles. e.g.

The tangent of the first point is Y/X = 2 and this angle is 63.4 degrees

The tangent of the second point is Y/X = 0.6667 and this angle is 33.9 degrees.

Subtract 33.9 from 63.4 and the angle between is 29.5 degrees.
