Question 747214
Consider the three points A = (7, -3), B = (9, 1), and C = (11, 0). Find the
length of each side of the triangle ABC.
----------------
{{{AB = sqrt(diffy^2 + diffx^2) = sqrt((-3-1)^2 + (7-9)^2) = sqrt(16 + 4)}}}
{{{AB = sqrt(20) = 2sqrt(5)}}}
AB =~ 4.472
--------------
Do the other 2 sides the same way.
