the any sides of figures.....
Congruent figures are similar - in sides as well as angles. Corresonding angles of similar figures congruent but their sides are not. The sides are all in some fixed ratio. [If that ratio is 1, the figures are congruent.]
Corresponding Sides
Here are some figures that have a number of sides that is a composite number:Two-dimensional figures includesquarehexagonoctagonnonagonThree-dimensional figures includetetrahedroncubeoctahedronicosahedron
2 dimensional (plane) figures can have three or more straight edges as sides. 3 dimensional (solid) figures can have four or more plane sides (faces). They can have fewer sides if the sides are not straight.
