A right triangle or a rectangle are polygons that have at least one right angle. There are other quadrilaterals and many irregular polygons that could have at lease one right angle, too. Many of them. Note that a polygon is any planar figure constructed of a finite number of line segments to make a closed figure. By that definition, which is a correct one, the triangle and rectangle are polygons. And a quadrilateral (of which the rectangle is special case) can be constructed with just one right angle, though it will be a bit quirky looking. Once we start adding sides to make different polygons, the game is afoot because so many possibilities exist.

What are polygons with at least one right angle?
There is no specific name, but "right-angled polygon" will suffice.
Shapes that have one right angle?
Any polygon can have just one right angle, from a right angled triangle upwards.
What is the properties of an right angle triangle?
right-angle triangle has at least one right angle .
What type of polygon has at least one angle greater than 180ΞΏ?
Any polygon with more than three sides may have an angle greater than 180 degrees.
Does a rhombus with at least one right angle have to be a square?
it wouldn't be a rhombus if it had a right angle.
What are polygons with at least one right angle?
There is no specific name, but "right-angled polygon" will suffice.
What is a polygon with one right angle?
Any polygon, if it is not regular, can have 1 right angle.
What polygon has one right angle?
A right angle triangle
What polygon doesn't have at least one interior angle that is right or obtuse?
The answer to this would be any acute polygon, such as an equilateral triangle. The definition of acute polygons is that no angle in the polygon is greater than or equal to 90 degrees.
What is the name of this polygon three sides one right angle?
right angle triangle
Which of the 2d shapes has a right angle?
Any polygon can have one right angle, for example, a right angled triangle.
Shapes that have one right angle?
Any polygon can have just one right angle, from a right angled triangle upwards.
What is the name for a polygon with three sides and one right angle?
A right triangle.
What is a 7 sided polygon with one interior right angle?
An irregular septagon: the right-angle will prevent it being regular.
What is the properties of an right angle triangle?
right-angle triangle has at least one right angle .
Is a right angle always a polygon?
A polygon is pretty much any enclosed shape constructed of straight line segments connected end to end. The angles do not have to be right. In fact, they usually aren't. A right angle would NEVER be a polygon, as it is just one right angle. In Euclidean geometry a right angle must be accompanied by two acute angles to form a triangle--the polygon with the smallest number of sides.
Do all parallelograms have at least one right angle?
The simple answer is no, not all parallelograms have at least one right angle. However, there are some that do. Rectangles and squares are 'special' parallelograms that all have at least one right angle.
