square
Quadrilaterals in general have four sides and four angles. Rhombuses, trapezoids, parallelograms, squares, rectangles, and other similar shapes are included among these.
I will rephrase your question as "What shape has only three right angles?" A shape is a 2D drawing that encloses some space. The sum of the angles must exceed 270 degrees. A rectangle is out of the question as it has four right angles. But a 5 sided shape with unequal sides (irregular pentagon) or higher number of sides is fine. I wish Wikipedia would let draw on these answers, because I could draw hundreds of shapes with three right angles. When we talk of shapes, the most regular shapes come to mind, triangles, squares, pentagons, etc. But you did not spcify that my shape had to have straight sides. Imagine, for example, a circle which I will break at three places and insert right angles. Weird, but it does have three right angles. Do the right angles have to face in towards the center? I could even draw a more bizarre shape with with three right angles facing out, connected by curved lines.
The sum of internal angles of a shape is given by the equation 180(n-2) where n is the number of sides. For a pentagon, which has 5 sides, this would be 180x3 = 540. The sum of external angles of a shape is given by (180-(x/n))n where n is the number of sides and x is the sum of internal angles. For a pentagon, this would be 5x(180-540/5) = 360
A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel. Hope this helps!
A shape with four sides and four internal angles is called a quadrilateral.
A shape that has four straight sides and four angles is defined as a quadrilateral. If all four angles are right angles, it is a rectangle, and if all four sides are congruent, it is a square.
A rhombus is a shape having two acute angles and four equal sides.
Quadrangle has four sides four angles and is ten letters long.
No shape has four equal sides and four different angles - either there are two pairs of equal angles, or all four angles are the same; or all sides are not the same length.
no, they can be any shape
Angles and sides are congruent when they are identical. A shape with four identical sides and angles is a square.
Squares and rectangles have a two-dimensional shape with four sides and four right angles.
