an equilateral triangle (all sides are adjacent and 60 degrees)
This is a rectangle.
A rectangle. If there are equal adjacent sides it's a square.It is a square or a rectangle both of which are 4 sided quadrilaterals

octagon
A shape with equal adjacent angles is a rhombus. In a rhombus, all four sides are of equal length, and each pair of adjacent angles are equal. This means that opposite angles are also equal, resulting in a symmetrical shape. Other shapes with equal adjacent angles include rectangles and squares, where adjacent angles are 90 degrees.
A shape with four sides of equal length but no right angles is a rhombus. In a rhombus, the opposite angles are equal, and the adjacent angles are supplementary, meaning they add up to 180 degrees. This characteristic gives the rhombus its distinctive slanted appearance, differentiating it from a square, which has right angles.
A shape with all its adjacent sides perpendicular is a rectangle or a square. In both these shapes, the angles formed between adjacent sides are right angles (90 degrees). A square is a specific type of rectangle where all sides are of equal length, while a rectangle can have sides of different lengths.
Adjacent angles define the shape and perception of the design.
A quadrilateral with no right angles and four equal sides is called a rhombus. In a rhombus, all sides are of equal length, but the angles are not constrained to be 90 degrees, allowing for various angles. This shape has opposite angles that are equal and adjacent angles that are supplementary. A square is a special case of a rhombus where all angles are right angles.
A shape with opposite sides parallel and of the same length and four right angles is a rectangle.
a pentagon
A shape that has four equal sides and opposite angles equal is a rhombus. In a rhombus, all sides are of equal length, and while opposite angles are equal, adjacent angles are supplementary (adding up to 180 degrees). A square is a special type of rhombus where all angles are also right angles.
If a set of equal sides are adjacent, then the quadrilateral is a "kite" shape. If a set of equal sides are opposite, then the quadrilateral is a parallelogram.
A rectangle has 4 sides not the same length and 4 right angles.
A shape that has four right angles is a rectangle. If all four sides are equal in length, then it is a square.
A rectangle is the only such shape. Not sure about the "little" right angles: all right angles are of the same measure.
