Rectangle is the exact answer. But if you want to be technical, a square could also be the answer.
Rhombus
rhombus
It depends on the actual shape of that octagon. It CAN have two pairs of parallel sides. A regular octagon has 4 pairs of parallel sides.
A rectangle
The shape that fits this description is a parallelogram. A parallelogram has two pairs of parallel sides, meaning that opposite sides are parallel. Additionally, a parallelogram does not have any right angles, as the sum of its adjacent angles is always 180 degrees. Examples of parallelograms include rectangles, squares, rhombuses, and rectangles.

No, it's a parallelogram.If there are 2 pairs of parallel sides AND all the sides are of equal length, it's a rhombusIf there are 2 pairs of parallel sides AND all the angles are of equal measure, it's a rectangle.If there are 2 pairs of parallel sides AND all the sides are of equal length, AND all the angles are of equal measure, then it's a square.
