In geometry, similar refers to two figures that have the same shape but may differ in size. Specifically, similar figures have corresponding angles that are equal and corresponding sides that are proportional in length.
similar shapes have corresponding angles that are equal. Also, any length in one shape is equal to the scale factor times the corresponding length in the other shape.
proportional
scale factor
Corresponding sides are congruent with one another, meaning they have the same length/measurement
If the scale factor is 1. That is, if a pair of corresponding sides are the same length.

Of the same length.

The two defining requirements of similar figures is that the corresponding angles are all equal and that the ratio of corresponding sides is a constant.So if you know the ratio, R, then draw a line parallel to a line of the first figure whose length is R*(length of line in first figure). At its end, draw an angle congruent to the corresponding angle in the first figure. Draw the other arm of the angle so that its length is R*(length of the corresponding line in the first figure). Continue until you return to the starting point.

You divide a length of one polygon by the corresponding length in the other polygon. Any length will do, as long as you use the corresponding length in both.

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.
