parallelagram
That's a rectangle (possibly a square). If two sides are parallel, and all angles are right angles, then the other two sides must be parallel also.
A rectangle has two right angles and parcel sides
A shape with parallel sides but no right angles is called a parallelogram
A right trapezoid is a four-sided polygon with two right angles and two parallel sides.
parallelagram
it is a square. the square has 4 sides. they all are the samelength. Two pairs of parallel sides. 4 right angles.
A parallelogram.
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)
A figure with four sides, two of which are parallel and with no right angles, is called a trapezoid (or trapezium in some countries). In this shape, the parallel sides are known as the bases, while the other two sides are called the legs. The angles between the legs and the bases can vary, which is why there are no right angles in this configuration.
Rhombus
rhombus
Yes and 4 right angles
