They are called SIMILAR.
A protractor is used to measure angles.
The angles for congruent shapes and the angles in similar shapes are all the same. All the sides are also proportional in both. Basically, all congruent shapes are similar but not all similar shapes are congruent.
regular polygons
Information that you have about one shape can be transferred to the other. For example, the measure of corresponding angles will be the same; the lengths of each pair of corresponding sides will be in the same ratio.
All corresponding angles are the same, and corresponding sides are proportional.
They need to have the same angles and proportional side lengths.
Similar shapes.
Yes, similar figures always have congruent corresponding angles and proportional corresponding side lengths.
Regular shapes have equal side lengths and equal angles
When two shapes have proportionally equivalent lengths and angles, they are geometrically similar. For example, take a triangle with sides of length 3, 4, and 5. Another triangle with side lengths 6, 8, and 10 would be geometrically similar to it because its angles are the same and its side lengths are proportional.
They have similar proportional shapes and the same angles.

The angles for congruent shapes and the angles in similar shapes are all the same. All the sides are also proportional in both. Basically, all congruent shapes are similar but not all similar shapes are congruent.
Two geometric shapes are similar if they have same size,shape, side lengths,and angles.
They are said to be irregular shapes or polygons
