To find a missing side length in similar figures, you can use the property that corresponding sides of similar figures are in proportion. Set up a ratio using the lengths of the known corresponding sides from both figures. For example, if the ratio of the sides of Figure 1 to Figure 2 is known, you can express the relationship as a proportion and solve for the missing side length. This can be represented mathematically as (\frac{a}{b} = \frac{c}{d}), where (a) and (b) are corresponding sides, and (c) is the known side from one figure, with (d) being the unknown side in the other figure.
It tells you how many times the side length will grow or shrink.
Divide the length of a side of one triangle by the length of the corresponding side of the other triangle.

similar figures have the same angles but not necessarily the same side lengths
You would look at the side lengths and the scale factor to find a pair of similar figures :)
The scale factor will depend on the side lengths. (Angle measures of the figures will be identical.) For example, if the smaller side had a length of 5 and the larger side had a length of 10 the ratio of the two figures would be 1:2.
The area scale factor is the square of the side length scale factor.

Divide the length of a side of one triangle by the length of the corresponding side of the other triangle.

When two figures are similar it means that its the same size and length and that they both have same features in other words it means that its congruent.Simply put :they have the same shape, same angles and proportional side lengths.
Corresponding sides of similar figures are proportional.
You need to know the proportionality constant, or ratio of the two figures. Suppose two corresponding sides have lengths of 10cm and 25cm, then the ratio is 25/10 = 2.5. If another side of the first figure is 6cm long, then multiply it by 2.5 to find the length of the corresponding side: 6cm x 2.5 = 15cm. If one side of the second figure is 30cm long, then divide it by 2.5 to get the length of the corresponding side in the first figure: 30cm / 2.5 = 12cm.
similar figures have the same angles but not necessarily the same side lengths
To find the scale factor, you need to compare the corresponding sides of two similar figures. The scale factor is calculated by dividing the length of a side on the larger figure by the length of the corresponding side on the smaller figure. For example, if the larger figure has a side length of 8 units and the corresponding side on the smaller figure is 2 units, the scale factor would be 8 divided by 2, which equals 4.
