a Rhombus...
No sides perpendicular means no right angles. A rhombus is a quadrilateral with no right angles so no sides perpendicular.
A Triangle drawn accross a sphere; NOT on a plane surface.
a shape with 5 sides and 2 right angles is or are a pentagon so the answer is a pentagon
The shape you are looking for is a quadrilateral. If you have a square, all angles MUST be right angles. A parallelogram can also have 4 equal sides in length and parallel sides, but a parallelogram doesn't have right angles.
hexagon and octagon.
a Rhombus...
A rhombus is one of them
A rectangle book has a rectangular shape, with four straight sides and four right angles.
A shape that has four straight sides and four angles is defined as a quadrilateral. If all four angles are right angles, it is a rectangle, and if all four sides are congruent, it is a square.
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
A shape with parallel sides but no right angles is called a parallelogram
A straight line
A RECTANGLE has 4 sides and 4 right angles.
This shape has only one pair of opposite sides and no right angles: <
If there are no angles, all you have is a 'straight side'. There is a plane and no shape. Maybe you are thinking that straight means standing up straight. You might then be thinking of an upright tube.
It is a 2-dimensional shape bounded by four straight sides, which meet at right angles.
