Question

What is the difference between a coordinate geometry proof and a proof method that does not require coordinate geometry. When would it be appropriate to use a coordinate proof rather than another proof method?

Answer 1

here's a page that explains coordinate geometry

http://www.regentsprep.org/regents/math/geometry/gcg4/coordinatelesson.htm

for things like distance formula, slope, etc

Answer 2

@jim_thompson5910 sorry to be bug but does not help with my confusion but thanks i guess :/

Answer 3

@Loser66 a little more help? or @jim_thompson5910 a little more help as well?

Answer 4

where are you stuck exactly?

Answer 5

does that page make sense?

Answer 6

I know how to do this i just don't know how to structure it how to write it out.

Answer 7

they just want you to compare/contrast the two kinds of geometry. List what they have in common, what makes them different. Also, maybe provide examples of each

Answer 8

I am still unsure i aam sorry but ill add in a testimonial for help in structuring it.

Answer 9

go ahead and post what you have so far and we'll work off that

Answer 10

Hmmm ok but if i need help just tag you correct?

Answer 11

yes you can tag me

Answer 12

What am i comparing?

Answer 13

Like i know what i am suppose to be comparing. Just can you help on simplifying of what i am suppose to be comparing

Answer 14

coordinate geometry and non coordinate geometry

Answer 15

coordinate geometry is geometry involving coordinates on the xy plane (so you can use the distance formula for instance)

Answer 16

Oh ok so i am explaining the differences and similarities between the 2 correct?

Answer 17

correct

Answer 18

oordinate proofs are more used when we deal with points in space for example we are given ponts say (x1,y1,z1),(x2,y2,z2) etc..in some cases we just use property of geometry to get to the answer

Answer 19

I quote that @jim_thompson5910

Answer 20

"Coordinate proofs use images on the coordinate plane and algebraic expressions to prove geometric concepts. In order to prove a coordinate, you must place the figure on a graph and use various formulas to validate statements made about the image. A triangle cannot be deemed a parallelogram until theorems and algebraic expressions provide sufficient proof."

Answer 21

yes and add to that

maybe add that you can find the slope or distance

Answer 22

Ok @AravindG

Answer 23

Had answer this before

Answer 24

But i cant use this

Answer 25

well don't copy and paste, you have to write your own response

Answer 26

Yea but i am overdue on this and its due in 8MIN

Answer 27

So i am running out of options ;(

Answer 28

plz @jim_thompson5910 help please

Answer 29

you'll just have to write something quickly and get it in before it's too late. I'm sorry you're out of time, but anything is better than nothing

Answer 30

just write about how coordinate geometry is used for things in the xy plane (again a good example is the distance formula)

Answer 31

@jim_thompson5910 i can ask for 10 more min but thats it so please help me ;(

Answer 32

noncoordinate geometry involves axioms like Euclid's axioms (eg: parallel postulate)

Answer 33

I am still confused on how to structure this ;(

Answer 34

have 2 paragraphs

one for coordinate geometry, another for noncoordinate geometry

then have a third paragraph for the similarities

Answer 35

Can you assist me in one of those paragraphs?

Answer 36

sure, but write out what you have so far

Answer 37

Ok

Answer 38

@jim_thompson5910 can you define coordinate geometry and ill do the Non coordinate geometry?

Answer 39

no, this is something you have to define in your own words. Give it a shot

Answer 40

:/ ok can you just define it for me like give me examples of coordinate geometry?

Answer 41

we can use coordinate geometry to find the distance of this line segment
