The only regular shape that has right angles is a square. A regular shape is one where all of its sides are the same length and all of its angles are the same angle.
A right triangle is a notably non-regular shape with a right angle, but this is due to its simplicity and some useful mathematical facts about it. You could basically cut any corner off of a square and get a non-regular shape with right angles. If your cut is shallow enough, you will get a pentagon. If it's too deep, you just get a right triangle. You can keep cutting corners off (preserving the "right" one) to get a figure of any number of sides. It'll just look weird.
No, right triangles do not.
right-angle triangle has at least one right angle .
Any polygon can have just one right angle, from a right angled triangle upwards.
Yes. A right angle is a two-dimensional feature, so while it can appear in obvious places (the corner of a cube has three of them), it can also appear in places that might not be so intuitive (the sharp corner of a cylindrical wedge has at least two, on the sides).
it wouldn't be a rhombus if it had a right angle.

Many shapes can have right angles, including rectangles, squares, and right triangles. Additionally, some polygons, like trapezoids and certain types of irregular shapes, can also contain right angles. The key characteristic of a right angle is that it measures 90 degrees, so any shape with at least one angle that meets this criterion can be considered to have a right angle. There is no specific limit to the number of shapes that can possess right angles, as they can be found in both regular and irregular forms.
Here's a list of shapes that need a right angle: square rectangle right triangle
No plane geometric figure can have one acute and three right angle only, at least two other angles must be included
Any polygon can have one right angle, for example, a right angled triangle.
Many shapes have a right angles. For example, a right angled triangle, square or rectangle all contain at least one right angle. Trapeziums may also contain right angles. Any irregular polygon may also contain a right angle.
A rectangle and a right trapezoid are two polygons that meet the criteria of having at least one right angle and at least one set of parallel lines. A rectangle has four right angles and opposite sides that are parallel, while a right trapezoid has one right angle and one pair of parallel sides. Both shapes exemplify the characteristics of right angles and parallelism in their structures.
No, right triangles do not.
False. Not all quadrilaterals have at least one right angle. While some quadrilaterals, like rectangles and squares, do have right angles, others, such as trapezoids, parallelograms, and rhombuses, may not have any right angles at all. Quadrilaterals can take on various shapes and angles, so the presence of a right angle is not a requirement.
