Answer 2

wel i need to prove this::
prove that a triangle whose vertices ae z1,z2 and z3 is equilateral iff z1^2+z2^2+z3^2^2-z1z2-z2z3-z3z1=0

Answer 3

how??

Answer 4

note z1,z2,z3 are complex numbers

Answer 5

Hmm Okay let me think about it

Answer 6

k

Answer 7

\[z_1^2+z_2^2+z_3^{2}-z_1z_2-z_2z_3-z_3z_1=0\]


Is this what we are supposed to prove?

Answer 8

yes

Answer 9

wow

Answer 10

Okay\[(z_1 + z_2 +z_3)^2 = 3(z_1z_2 + z_2z_3+z_3z_1)\]

Answer 11

\[z_1 z_2 + z_2z_3 +z_3z_3 \ge 0 \]

Answer 12

Now I need to think more lol

Answer 18

2.If 2 triangles whose vertices are z1,z2,z3 and w1,w2,w3 are similiar prove that
w1(z2-z3)+w2(z3-z1)+w3(z1-z2)=0

Answer 19

HELP

Answer 20

are those verticess complex
