They are similar shapes.
figures that are congruent have the same shape
A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape). The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.
Any figure or shape that does not have four sides.
The figures which are having exactly same size and shape are termed as convenient figures
a irregular figure is not a particular shape it may have two or more figures in to make a irregular figure
Congruent figure(s) (shapes) are two figures that have the same size AND shape.
A similar figure is proportionally the same shape as another figure and all the angles are the same.
3D is a term used to describe space figures. They occupy space and have volume. A 3D shape is also called solid figure , solid shape , space figure and 3D figure.
In order for a figure to be congruent, it has to be the same shape and size.
Most figures are not equilateral. If any two sides of a shape are of different length then the shape is not equilateral.
Your question is not clear. Please reword and clarify. similar=two figures that have the same shape, but not necessarily the same size
