A polygon with four sides that has equal opposite sides parallel and four equal angles is called a rectangle. In a rectangle, opposite sides are both equal in length and parallel, while each of the four angles measures 90 degrees. If all four sides are also equal in length, the rectangle becomes a square.
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
The description fits a square or a rhombus. In a square, all sides are of equal length, opposite sides are parallel, and all angles are equal (90 degrees). In a rhombus, all sides are also of equal length and opposite sides are parallel, but the angles are not necessarily equal, as they can vary while remaining equal in opposite pairs.
They may, or may not, be equal. If you are talking about a regular polygon, all angles are equal in measure. If it is not a regular polygon, the angles are most likely different.
Opposite sides are parallel; opposite sides are equal; opposite angles are equal.
parallelogram
A parallelogram. (A rectangle if the angles are 90o)A parallelogram (which may also be a rectangle, if all four angles are equal to 90°)
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
The given description fits that of a square which has 4 equal sides, opposite sides are parallel and it has 4 interior right angles
square
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
trapezoid is the answer!
rhombus
They may, or may not, be equal. If you are talking about a regular polygon, all angles are equal in measure. If it is not a regular polygon, the angles are most likely different.
Rectangle
No. A parallelogram, for example, is not a regular polygon. Even a rhombus, with parallel sides of equal lengths is not.
