How To Find Similar Polygons Learn how to identify and use similar polygons, which have the same shape but not the same size. find the scale factor and use it to solve for missing side lengths, perimeters, areas, and other measures with 23 step by step examples and a video lesson. In mathematics, a pair of polygons are said to be similar when their: corresponding angles are congruent. corresponding sides are proportional. the symbol ∼ is commonly used to represent similarity. let’s take an example of two squares given below, similar polygons. the four interior angles of one square are identical to the other.
How To Find Similar Polygons Definition. similar polygons. two polygons with the same shape, but not the same size. the corresponding angles of similar polygons are congruent (exactly the same) and the corresponding sides are proportional (in the same ratio). in similar polygons, the ratio of one side of a polygon to the corresponding side of the other is called the scale. Scale factor = perimeter of larger polygon perimeter of smaller polygon. scale factor = longer length of polygon 1 shorter corresponding length of polygon 2. in similar triangles, the ratio of the areas is equal to the square of the ratio of the corresponding sides. the same goes for two similar polygons for n > 3. Similar polygons. two polygons with the same shape are called similar polygons. the symbol for “is similar to” is ∼. notice that it is a portion of the “is congruent to” symbol, ≅. when two polygons are similar, these two facts both must be true: corresponding angles are equal. the ratios of pairs of corresponding sides must all be. Similar polygons are two polygons with the same shape, but not necessarily the same size. similar polygons have corresponding angles that are congruent, and corresponding sides that are proportional. these polygons are not similar: think about similar polygons as enlarging or shrinking the same shape. the symbol ∼ is used to represent similarity.

In the figure below, all three polygons are similar. starting with the polygon on the left, the center polygon is rotated clockwise 90°, the right one is flipped vertically. this is illustrated in more depth in "similar triangles", but is true for all similar polygons, not just triangles. in the figure at the top of the page, click 'reflect'. Recall that, given two similar polygons, the scale factor of similarity is the constant ratio of the length of the corresponding sides. since 𝐶 𝐷 and 𝑊 𝑍 are corresponding sides, the scale factor is given by 𝑊 𝑍 𝐶 𝐷 = 5 3 1 1 = 1 0 7 2 2. i n i n. this gives us the scale factor of 1 0 7 2 2.
