Isometry is a bijective function (transformation) which transforms figure $\displaystyle F_1$ into figure $\displaystyle F_2$ while preserving congruence of line segments.

Formally, for every two pair of points $\displaystyle (A,B)$ and $\displaystyle (A_1,B_1)$

$\displaystyle I(A) = A_1 \wedge I(B) = B_1 \Rightarrow A_1 B_1 = AB$ - Jan 19th 2007, 12:51 PMsymmetryOkay
Good replies.

OReilly, don't get too technical.

Let's keep things simple. - Jan 19th 2007, 01:49 PMOReilly

Math is not simple.

You are right, OReilly.
