Answer :
Symmetry: When two or more parts are identical after a flip, slide or turn.
A proportion is an equation with a ratio on each side.
Answer:
symmetry is like having the same exact thing on both sides and proportion is like a ratio of one thing to another. for example, if I had 4 apples and 8 oranges, the ratio would be 1:2 because for every apple there is, there would be 2 oranges.. hope that helps
