rectangle or square
Not possible - a flat shape with a minimum of four sides must have at least two angles of 90 degrees or larger.. Unless you're allowing 3-D shapes, in which case, a triangular-based pyramid would have four sides, but the angles at the corners would all be less than a right-angle.
A rhombus has 4 equal sides. Its angles can be right angles, but don't have to be. A square is a type of rhombus.
A square has four perpendicular sides.
An octagon has 8 sides and 8 angles.
It is impossible to have a six sided shape with right angles since the lines would never meet, therefore it would not create a shape. The most right angles you can have in a shape is four. A six sided shape is called a hexagon. There are Regular Hexagons, meaning all the sides and all the angles are equal. Any other Hexagon with unequal sides and angles and called Irregular Hexagons. Each side must be straight, and the sum of the angles equaling 720°.
Both statements are not always true. A square is a rectangle (a shape four sides and four corners which are all right angles) but a rectangle is not necessarily a square (a shape with four equal sides and four corners that are all right angles).
A shape with eight right angles is typically referred to as an octagonal shape, particularly if it has eight sides. However, if it specifically has eight right-angle corners, it may also be considered a type of polygon, such as a non-convex octagon, depending on how the angles are arranged. If all sides are equal and all angles are right angles, it can be described as a square or rectangular configuration with additional segments.
A shape with nine corners is called a nonagon. In geometry, a nonagon is a polygon that has nine sides and nine angles. It can be regular, where all sides and angles are equal, or irregular, where the sides and angles are not necessarily equal.
A shape that has four sides and four corners but is not a square is a rectangle. Rectangles have opposite sides that are equal in length and all angles are right angles, just like squares, but the adjacent sides can differ in length. Another example could be a trapezoid, which has one pair of parallel sides and can also have four corners.
A shape with eight sides is always an octagon. If all angles and sides are equal, it is called a regular octagon.
A shape that has square corners but not three sides is a rectangle. Rectangles have four sides and feature right angles, which are the square corners you're referring to. Other examples include squares, which are a specific type of rectangle, and other quadrilaterals that may also have square corners.
Well, isn't that a happy little question! A shape with 2 square corners is called a rectangle, my friend. It's like a square, but with two sides longer than the other two. Just imagine all the beautiful landscapes you could create with rectangles in your paintings!
A better name for "corners" would be angles, but the shape's name would be a hexagon
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
A shape with 8 sides is called an octagon. If it has 4 right angles, it can be classified as a right octagon, which is a specific type of octagon where some angles are right angles. However, a regular octagon does not have right angles; thus, a shape with 8 sides and exactly 4 right angles may be an irregular octagon. An example could be a shape resembling a rectangle extended into an octagonal form.
A 4 sided polygon is called a quadrilateral. Depending on where the two right angles are, would put the quadrilateral into different subsets. For example if the two right angles are on adjacent corners (and the other 2 angles are not right angles), then it is a trapezoid. If the 2 right angles are in opposite corners, and the other 2 angles are not right angles then it would be a kite-shaped quadrilateral.
A shape with parallel sides but no right angles is called a parallelogram
