a square and a rectangle
It all depends on the shape; different 2D geometrical shapes have different characteristics.Some specialized geometrical shapes:Square: 4 sides; 4 equal sides; 2 pairs of parallel sides; 4 right angles (90 degrees)* A square is a rectangle.Rectangle: 4 sides; 2 pairs of parallel sides; 4 right angles (90 degrees)* A rectangle is not a square.Triangle (equilateral): 3 sides; 3 equal sides; all angles 60 degreesTriangle (isosceles): 3 sides; 2 equal sides (usually the base is the odd one)Triangle (scalene): 3 sides; all uneven sides and anglesRhombus: 4 sides; 4 equal sides; 2 pairs of parallel sides; 4 equal anglesParallelogram: 4 sides; 1 pair of parallel sidesThese are the basic geometrical 2D shapes, but there are others that are more complex.
A quadrilateral with 4 equal sides and 4 right angles is a square.
The shape you are looking for is a quadrilateral. If you have a square, all angles MUST be right angles. A parallelogram can also have 4 equal sides in length and parallel sides, but a parallelogram doesn't have right angles.
A square shape for example has 4 right angles and a right angle is 90 degrees.
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.
it is the square
There is no shape with exactly 4 right angles and 2 congruent sides.A rectangle has 4 right angles and 2 pairs of congruent sides - 4 sides in all. But if the numbers in the question are not limiting, then there are many more shapes. An irregular hexagon with the following shape, will meet the requirements if its height is the same as its base.___|....\|......\___!_______|There are lots more shapes with more sides.
definitely a pentagon can.. It can be any shapes that have more than 4 sides except that they can't be regular shapes.
a square and a rectangle
Squares
Both shapes have 4 sides, 4 right angles and 2 parallel pairs of lines.
A RECTANGLE has 4 sides and 4 right angles.
... A square? ~Singer
A square. Its opposite sides are equal and it has 4 right angles.
A rectangle the same number of sides & angles. (4 sides & 4 right angles)
Rhombus has 4 equal sides and no right angles
