I am a polygon with four sides and no right angles. What am I?
A trapezoid, a parallelogram, or a rhombus.
Which name best describes parallelogram with four congruent angles?
A parallelogram with 4 equal right angles is a rectangle.
A parallelogram with four equal sides but no right angles?
it is a rhombus
What has 4 equal sides its opposite sides are parallel and its angles may be right angles?
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.
What quadrilateral has one pair of parallel sides and no right angles?
There are actually two answers. parallelogram and trapezoid. No. wait, a square or rectangle is a parallelogram, so I can't rule out that entire class. I guess you are left with trapezoid. Oh wait, a trapezoid can have two right angles and still fit the definition, so I can't rule out that entire class. A non-right triangular section would fit. A non-right trapezoid would be the same thing, I guess. A non-right parallelogram would also work.
