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
circles
A square, by definition, must have four right angles. A plane shape with 4 right angles which is not a square is a rectangle.
No polygon can have less than 3 angles. It would be a triangle with 3 sides but that has 3 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°.
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.
If the question is about a plane shape with exactly 3 right angles it could be an irregular polygon of 5 or more sides. If the shape can have more than 3 right angles then a square or rectangle are also possible. Finally, in 3 or more dimensions, a polyhedron with any number of faces can have 3 or more right angles.
A seven sided shape is a heptagon.
No because a parallelogram in the shape of a rectangle has 4 right angles
You can make a four sided shape with 3 right angles, but it must have another right angle, too. So technically, yes.
A rectangle has two right angles. In a rectangle, opposite sides are equal in length and all interior angles are 90 degrees. This geometric property distinguishes a rectangle from other shapes, such as squares or parallelograms, which may also have right angles but do not necessarily have exactly two right angles.
a Pentagon is five sided and CAN have 3 right angles.
you cannot make a regular shape which has 3 right angles only, you will always end up with 4 right angles
A irregular hexagon
A heptagon.
a triangle a triangle
irregular hexagon?
No. The sum of the angles in any 4-sided shape must all ways add up to 360 degrees. So if 3 of the angles in such a shape are right angles the 4th must be as well, which would make the shape a rectangle.
