no a quadralateral shape is simply a shape with 4 sides. (quad means 4)
a quadrilateral where each angle is a right angle
No , a parallelogram can not have a 90 Degree angle .Reason : A Parallelogram can be defined as a quadrilateral whose two s sides are parallel to each other and all the four angles at the vertices are not 90 degrees or right angles, then the quadrilateral is called a parallelogram.
Each angle in a square is a right angle, or a 90 degree angle.
A square is a type of parallelogram which is a type of quadrilateral which is a polygon.from WikipediaA convex quadrilateral is a square if and only if it is any one of the following:[2][3]a rectangle with two adjacent equal sidesa quadrilateral with four equal sides and four right anglesa parallelogram with one right angle and two adjacent equal sidesa rhombus with a right anglea rhombus with all angles equala quadrilateral where the diagonals are equal and the perpendicular bisectors of each other, i.e. a rhombus with equal diagonals
In geometry, a cyclic quadrilateral is a quadrilateral whose vertices all lie on a single circle. The vertices are said to be concyclic. In a cyclic quadrilateral, opposite angles are supplementary (their sum is π radians or 180°). Equivalently, each exterior angle is equal to the opposite interior angle. The area of a cyclic quadrilateral is given by Brahmagupta's formula as long as the sides are given. This area is maximal among all quadrilaterals having the same side lengths. Ptolemy's theorem expresses the product of the lengths of the two diagonals of a cyclic quadrilateral as equal to the sum of the products of opposite sides. In any convex quadrilateral, the two diagonals together partition the quadrilateral into four triangles; in a cyclic quadrilateral, opposite pairs of these four triangles are similar to each other. Any square, rectangle, or isosceles trapezoid is cyclic. A kite is cyclic if and only if it has two right angles. ----Wikipedia
rectangle
It is a square or a rectangle where each interior angle is a right angle of 90 degrees.
a square or a rectangle
A rectangle or a square.
That is called a rectangle.
A square or a rectangle
A quadrilateral with all right angles is a rectangle.
A rectangle, or perhaps a square.
A square or a rectangle
The answer to this question is really straight forward........square! Obviously.
A rectangle, or could be a square if lengths are the same.
Either a square or a rectangle
