Talk:Congruence (geometry)

From Wikipedia, the free encyclopedia

[edit] A handy mnemonic

An easy way to remember that SSA (Side-Side-Angle) does not prove congruence for triangles is to simply reverse the order of the letters. --Jediknil

[edit] Equality

"In less formal language, two sets are congruent if they have the same shape and size, but are in different positions (for instance one may be rotated, flipped, or simply moved)."

Should we specify two different sets? Every set is congruent to itself.--Syd Henderson 01:16, 22 September 2006 (UTC)

[edit] SSA

Should we include a diagram showing how SSA doesn't work? Just a suggestion. Altopian

asa sas sss are congruence theorem but ass aaa saa aas are not
