Not necessarily. A parallelogram is a quadrilateral with 2 sets of 2 parallel sides. Only rectangles and squares have right angles as all four angles - a rectangle is a "special" parallelogram that has all four angles equal; a square is a "special" rectangle that has all four sides of equal length.
a quadrilateral
It can, but they can also all be the same.
A rectangle is generally defined as a quadrilateral with four right angles. No rectangle can have four different side lengths by that definition. Finding the area of such a shape is therefore impossible.
A square, by definition, must have four right angles. A plane shape with 4 right angles which is not a square is a rectangle.
-- Every quadrilateral has four sides.-- If it has no right angles, then it could be a parallelogram, a rhombus,a kite, a trapezoid, or any non-regular quadrilateral.
A regular quadrilateral is a square. It is a four-sided figure with all sides being the same length and all angles equal (right angles).
A regular quadrilateral. A plane shape with four sides which are equal in length and which meet at right angles.
A square is a quadrilateral with four equal sides and four right angles.
A rhombus is not a pentagon, it's a quadrilateral.
All quadrilateral have four angles. It is possible that all four angles are right angles, even if the quadrilateral is not a square (this would be a rectangle).
A quadrilateral with four right angles is a rectangle. If all its sides are the same then it is a square.
A quadrilateral having four right angles is called a rectangle.
A quadrilateral can have four right angles.
A quadrilateral is any linear shape which contains four straight lines connected at four angles. the total degrees found within the angles total 360 degrees.A regular quadrilateral is a square : all four sides have equal lengths and all four angles are equal, thereby right angles of 90° each.
