Math help :)
Okay whoever can help is a genius
How do you find
The length of a line segment
midpoint of a line segment
definition of a median (unless its the below thing)
and how do you join the opposite verticy to the midpoint!
Kill it, then steal its wallet.
You really need help with this?
How old are you?
I can give you the first three, but what are you asking in the last one?
Gimmie what you can lol
I wanna do this myself but I have 4 projects to do, and 3 tests to study for (this is one of them) and I dont want to look through 200 pages of notes, so I just need quick help
You need to tell me what info you have in the first place.
For the first one ((deltaX)squared + (deltaY)squared + (deltaZ)squared)^(1/2)
For the second the point is (detaX/2, deltaY/2, deltaZ/2)
Median is the number that is assigned the nth place in a series (ordered from lowest to highest) where n is the number of entries in the series divided by 2 and then sumed with 1/2, if there is no number that fits this definition (the series has an even number of entries), then the number is the average of the two numbers that is nearest to the nth number (since in this case n would be an the sum of an integer and 1/2).
I didn't use wikipedia, and I didn't bother to insert the right symbols for delta and powers.

lenght of a line segment = Distance = square root of ( (x1 - x2)^2 + (y1-y2)^2 )

Definition of median = order your group from highest to lowest. The number in the middles is the median.
the last one.. erm.. give me an example what you're talking about. you mean angles & bisecting??
You in pre-algebra or something?
Its something to do with joining 2 midpoints or something...
Edit: to mojo, were doing a review unit of everything prior to our actual course work, but ive pretty much forgoten it all
PS: Thanks alot CPR and adonai
