Maths a level vectors
Hi TSR,
I am stuck on this vector question:
The vertices of a triangle MNP have coordinates:
M (-2, 0, 5)
N (8, -5, 1)
P (k, -2, -6)
Given that triangle MNP is isosceles and k is positive integer, find the value of k.
Also, how do you know which sides are the same? (How do you know that MN = MP and why can’t MN = NP)
Thanks for your help
