A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.
A parallelogram is a four sided polygon with opposing parallel sides of equal length. Then if it has four right angles, the polygon becomes a rectangle.
It would be a rectangle.
a parallelogram is a 4 sided polygon with two pair of parallel sides. So squares and rectangles are parallelograms since they have 2 pair of parallel sides and yes they have right angles, BUT most parallelograms do not have right angles. So the answer is it may have them, but does not need to have them
A rhombus. More information... The no right angles is throwing me, but I will add this comment: A square A four-sided polygon having equal-length sides meeting at right angles. The sum of the angles of a square is 360 degrees. A Parellelogram is a four-sided polygon with two pairs of parallel sides. The sum of the angles of a parallelogram is 360 degrees. A Rhombus is a four-sided polygon having all four sides of equal length. The sum of the angles of a rhombus is 360 degrees. So, a Square is actually a Parellelogram and Rhombus as well; and it has 4 right angles. So... I am not sure that Parellelogram and Rhombus are what you were looking for,
A right trapezoid is a four-sided polygon with two right angles and two parallel sides.
A parallelogram has 2 pairs of parallel sides.
parallelogram
A rhombus or a parallelogram
A pallelogram or rhombus
The given description fits that of a square which has 4 equal sides, opposite sides are parallel and it has 4 interior right angles
A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.
A rectangle is a quadrilateral with opposite sides parallel and congruent and four right angles. If all four sides are congruent, it is a square.
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
it's a trapezoid
A triangle having all angles less than 90 degrees is a polygon having no parallel sides and all acute angles.
A parallelogram is a four sided polygon with opposing parallel sides of equal length. Then if it has four right angles, the polygon becomes a rectangle.
