1 Geometry Question Check Pls! Will Award Medal!!
According to @Phi the answer is not 2a.

Answer 1

@Nitroster what did you get? btw phi is correct

Answer 2

\[L_{(0,0)-(a,a)}=sqrt((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2})\] You should be able to use know values from here and solve.

Answer 3

or I should say, how did you get 2a anyway?

Answer 4

My work is as follows...
√(a - 0)^2 + (0 - a)^2
√a^2 + a^2
STUCK THERE

Answer 5

hmm did youj see what twvogels posted? are those your coordinates?

Answer 6

Answer 7
