If only right angles, then the answer is squares and rectangles.
If one or more right angles, the answer will include trapezium, kite and any (irregular) polygon with 5 or more sides.
A single triangle can have only one right angle, but several triangles can have right angles, (sorry, that's purely a linguistic argument).
Triangle, square, and pentagon
It is called a square or a rectangle, however a rectangle is just a streched square.
Square rectangle rhombus parallelogram
Six names that you can call a square are rhombus, square, rectangle, kite, trapezoid, or parallelogram. All of these shapes have four corners and are known as quadrilaterals.

a rhombus
Triangle, square, and pentagon
Shapes with no names are typically referred to as "irregular shapes." These shapes do not have specific labels such as circle, square, or triangle, as they do not conform to any standard geometric definition. Irregular shapes can have varying sides, angles, and measurements, making them unique and not easily categorized.

Square rectangle rhombus parallelogram
There are several different types of shapes. A few of the shapes are octagon, square, hendecagon, circle, polygon, and trapezium.

Regular square: A square with all equal sides and right angles. Rectangle: A square with all right angles but unequal sides. Rhombus: A square with all sides equal in length but angles are not necessarily 90 degrees.
A square is a quadrilateral with four equal sides and four right angles. It is also known as a regular quadrilateral or a regular tetragon. In geometry, a square can also be referred to as a rhombus (a quadrilateral with all sides of equal length) or a rectangle (a quadrilateral with opposite sides of equal length and all angles equal to 90 degrees).
Square, rectangle, rhombus, kite and most parrallelagrams
A square is a plane rectangle with four equal sides and four right angles, a four-sided regular polygon, and a rhombus having four right angles.
A square is a four-sided polygon with four right angles. Some boy's names that rhyme with square are Thayer, and Lar (short for Larry), and Gar (short for Garrett).
