triangle
The only shapes that fit that description would be a rectangle or a square.Improved Answer:-A trapezoid could have two right angles, an acute angle and an obtuse angle with a pair of parallel sides.
No, parallel lines do not meet at a right angle. In theory, parallel lines never meet. In practice, parallel lines on earth could meet at the North Pole and/or the South Pole. Perpendicular lines meet at a right angle.
Well, parallel lines are a pair of lines that could go on forever without intersecting. They could be going in the vertical direction or in the horizontal direction. I'm going to list a few shapes; circle triangle I'm sure there are more, but those are the only ones I could think of at the top of my head.
A kite could fit the given description.

triangles squares rectangles i think most shapes could have a 90 degree angle except a circle

It could be a right angle triangle
The only polygon that absolutely positively never has any parallel sides is a triangle. Any other shape comprised of four or more straight line segments could have one or more pairs that are parallel.
It could be a trapezoid having 2 right angles, an obtuse angle and an acute angle
It could be a trapezoid providing that the other two angles are an acute angle and an obtuse angle
As defined, a quadrilateral. Could be others, but need to know about parallel and/or equal sides...
Squares, rectangles, and some triangles, most commonly. Any polygon could have a right angle if it is irregular.
A parallelogram has 2 pairs of parallel sides, and provided that it isn't a square, it has no square corners. If necessary, you could call it an "oblique parallelogram" to indicate that it isn't square.
