squares, right triangles, rectangles
A square shape for example has 4 right angles and a right angle is 90 degrees.
The most basic answer would be a square, which is both symmetrical and regular. However, rectangles are also symmetrical, as are hexagons with two opposing 90° angles and four matching 135° angles. In fact, the number of potential shapes are infinite, unless you specify exactly how many right angles the shape must have.
A square and a rectangle have 4 interior right angles also a right angle triangle has 1 right angle of 90 degrees
All polygons can have right angles except for circle and ovulated shapes. The only 'regular polygon' that has a right angle is the quadrilateral.

wich shaps have right angles
Most shapes have no right angles. Circle, pentagon, hexagon etc. Ones that do include the square and some triangles.

Triangles
The diagonals of a square and a rhombus cross at right angles.

Shapes that do not have right angles include circles, ovals, and various types of polygons such as triangles (specifically acute and obtuse triangles), and irregular polygons. Additionally, shapes like ellipses and curves, such as parabolas, also lack right angles. These shapes can have angles of varying degrees, but none equal to 90 degrees.
Shapes that do not have any right angles or angles are typically referred to as "curvilinear" shapes. Examples include circles, ellipses, and ovals, where the boundary is smooth and continuously curved without any vertices or corners. These shapes are defined by their curves rather than angular measurements.
Shapes that do not have right angles include circles, ellipses, and many polygons, such as triangles and irregular shapes. For instance, an equilateral triangle has three angles that are each 60 degrees, while a circle has no angles at all. Additionally, shapes like ovals and curves also lack right angles. Overall, many geometric forms can be created without incorporating right angles.
