It is a square or a rectangle
Opposite sides are parallel. Opposite angles total 180 degrees.
A rhombus is a 4 equal sided quadrilateral with opposite parallel sides and equal opposite acute angles and equal opposite obtuse angles that all add up to 360 degrees.
quadrilateral--a four-sided figure, any length sides, any angles trapezoid--one pair of parallel sides, any length sides, any angles parallelogram--two pairs of parallel sides, opposite sides congruent, opposite angles congruent rectangle--two pairs of parallel sides, opposite sides congruent, all angles are right angles (90 degrees) rhombus--two pairs of parallel sides, all sides congruent, opposite angles congruent square--two pairs of parallel sides, all sides congruetn, all angles are right angles (90 degrees)
The opposite angles of a quadrilateral inscribed in a circle are supplementary, meaning they add up to 180 degrees. This is due to the property that the sum of the opposite angles of any quadrilateral inscribed in a circle is always 180 degrees. This property can be proven using properties of angles subtended by the same arc in a circle.
I am a rectangle.
It is a quadrilateral whose opposite sides are parallel and has no right angles
square
It is not possible for a quadrilateral in Euclidean plane geometry to have no equal angles and still have its opposite sides parallel.It's possible for a quadrilateral to have no equal angles and two of its sides parallel (opposite ones, obviously; adjacent sides can't possibly be parallel). That would be a trapezoid.
a rectangle is a parallelogram with all the angles measuring 90 degrees. a parallelogram is a quadrilateral with opposite sides parallel to each other.
rhombus
its a shape
A parallelogram is a 4 sided quadrilateral that has two pairs of opposite parallel sides and two equal opposite acute angles and two equal opposite obtuse angles whereas the 4 angles add up to 360 degrees.
