Grade 11 analytical geometry: 4th Co-ordinate of parallelogram

In this lesson we will look at parallelograms within grade 11 analytical geometry. How to find the 4th co-ordinate of a parallelogram.

Hey Kevin❤️great video and truly the simplest way but i showed my teacher this and he said if i use this way im not going to get full marks so could you please show us how to get the Coordinate using calculations

[mimimichelle]

I just love your videos, i mean you are audible and good at teaching ❤️❤️❤️

[JuniorElijah-orkr]

Kelvin wouldn't the midpoint formula work here because we looking for d

[Tee]

1:22 or u could use diagonals bisect and find the mind point, then use the midpoint to find the other points like in the previous vid

there r questions that clearly say calculate so u obviously cant use inspection

[Chronos]

wouldnt the midpoint formula also work ?

[tshepangBaptista-lsiq]

Sir may you perhaps add another method because I tried using inspection in one of my tests and I got a 0 because that isn't how we are supposed to get a co-ordinate "appearantly"

in the second example why did you look at how the x and y values changed from A to B because in the first example you looked at how they changed from B to A?

[officixl_shii.bqxx.ii]

Hii Mr Kevin.well i get how you did everything but i am getting different answers when i use A and C than when im using A and B for the second part as from A to B it decreased by 3 but from A to C it decreased by 2

[LisakhanyaNojavu]

I still don't understand, like do you go from A to B or you just choose which way you want to start to and go to 😢

[dakzinboy]

Omg 🙆🙆 that's tricky way can u show the whole calculations on how you got these coordinates I mean is it required to use any formula to get these coordinates

[khanyisilemngomezulu]

What if the answer is located 4 marks and this method seems to short

This video does not help, you are taking short cuts
