Congruency means that the given 2 figures are exactly same in shape and size. Thus all corresponding angles will also be the same.Similarity of shapes means that the 2 given shapes are same in shape but the measures of corresponding sides may not be the same. Since the shapes are the same, the corresponding angles are also same.If 2 shapes are congruent, they have equal corresponding angles. The equal angles satisfy the condition for the shapes being similar. Hence congruent shapes are similar as well.
square
They can have some (or all) equal angles. A rectangle, for example, has all four angles equal but, because its sides are not the same measure, it is not a regular shape.
It is a rhombus which has 2 equal acute angles and 2 equal obtuse angles
The shape that has 4 equal sides, 2 acute angles, and 2 obtuse angles is a kite. In a kite, the two pairs of adjacent sides are equal in length, creating the four equal sides. The acute angles are formed between the unequal sides, while the obtuse angles are formed between the equal sides.
Regular shapes have equal side lengths and equal angles

square
That's three different shapes: a rectangle, a rhombus and a trapezoid respectively.
Squares
They can have some (or all) equal angles. A rectangle, for example, has all four angles equal but, because its sides are not the same measure, it is not a regular shape.
All right angles will be equal as they are all 90O. Shapes that have 4 right angles will be rectangles (which include squares).
some shapes tile and some don't because if the side angles don't equal a factor of 360 degrees it will not tile and if the side angles do equal a factor a 360 degrees it willtile.
No but it has 2 equal acute angles and 2 equal obtuse angles
Squares
Equilateral triangle.Also a square.Also a regular pentagon.Also any regular polygon of any number of sides.A shape with equal sides and angles is a called a regularshape.[But there are also other shapes, such as a rhombus, which has equal sides but is not a regular polygon because it does not have equal angles. There is no collective name for such "squashed" polygons".]
It could be a parallelogram, but there are other shapes with more sides.
