What makes 2 polygons congruent

If you can move them, turn them over and stack them exactly on top of each other, then they are congruent. To see this, click on any polygon below. It will be flipped over, rotated and stacked on another as needed to demonstrate that they are congruent. The three types of operation above are called 'transforms'. In the video below we are going to review how to solve proportions, determine if two polygons are similar by creating scale factors, and learn how to solve for unknown measures.

Corresponding sides must be proportional. So what that means is if I said that these two figures were similar, that is if a, b, c, d, e and I'm going to write that over here. If a, b , c, d, e pentagon and this figure f, g, h, I, j, g, h, i, j are similar, notice it kind of looks like a congruence marking except for we do not have the equal sign.

So if you just have Mr. Squiggles all by himself, then that means that they're similar. So what that means is that the ratio of ab:fg is the same as bc:gh of cd:hi and so on. Symmetries of Parallelograms. What Is a Regular Polygon? Properties of Parallelograms.
