a square
Answer:
Assuming the question 's answer is an enclised figure with only 3 90o angles, a multitude of shapes have 3 right angles whether you consider 2 or 3 dimensional objects. A three sided pyramid (one of the vertexes of a cube passing through a plane) would meet the criteria. On a plane manys polygon can have 3 right angles with the other angles totaling 90o. On the surface of the Earth a set of lines can be established that are 90o to the equator that meet at the north pole at 90o as well

What shape does not have right angles?
circles
What is a counterexample for a square with four right angles?
A square, by definition, must have four right angles. A plane shape with 4 right angles which is not a square is a rectangle.
What shape has 3 sides and 2 angles?
No polygon can have less than 3 angles. It would be a triangle with 3 sides but that has 3 angles.
What is the name of a six sided shape with all right angles?
It is impossible to have a six sided shape with right angles since the lines would never meet, therefore it would not create a shape. The most right angles you can have in a shape is four. A six sided shape is called a hexagon. There are Regular Hexagons, meaning all the sides and all the angles are equal. Any other Hexagon with unequal sides and angles and called Irregular Hexagons. Each side must be straight, and the sum of the angles equaling 720°.
What shape has more than 3 sides and all angles are smaller than a right angle?
Not possible - a flat shape with a minimum of four sides must have at least two angles of 90 degrees or larger.. Unless you're allowing 3-D shapes, in which case, a triangular-based pyramid would have four sides, but the angles at the corners would all be less than a right-angle.
