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
a Rhombus...
Parrallelogram
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 shape with opposite sides parallel and of the same length and four right angles is a rectangle.
a pentagon
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.
This is a rectangle.
