A figure with three right angles is a type of polygon known as a right-angled triangle or a right triangle. Specifically, if it has three right angles, it cannot exist in Euclidean geometry because the sum of the interior angles of any triangle must equal 180 degrees. However, in certain non-Euclidean geometries, such as spherical geometry, a triangle can have angles that sum to more than 180 degrees, potentially allowing for a figure with three right angles. In practical terms, such a figure would typically be considered impossible in standard Euclidean space.
A six-sided figure with three right angles is known as a trapezoid or trapezium, depending on the region. Specifically, if it has three right angles, it can be visualized as a shape resembling a rectangle with one of its corners "cut off." This creates a polygon that still has six sides but deviates from traditional rectangles or squares. The specific arrangement of sides and angles can vary, but the key characteristic is having three right angles.
Yes, my attempt at text art, below, is a 5-sided polygon (pentagon) with 3 right angles. _ | \ |_|
It doesn't have to, but it can. A trapezoid is any shape in which there is a pair of parallel sides. This means that a square can be classified as a trapezoid. But notice that a four-sided shape can never have ONLY three 90° angles. The sum of angles of a four-sided shape is 360--this means that if you have three 90° angles, then the remaining angle must be 360-3(90) which is 90°, giving you four right angles. * * * * * No you cannot. As indicated in the second paragraph of the above answer, three right angles implies that all four angles are right angles and that makes the figure a rectangle (or a square).

A rhombus, an equal sided parallelogram or an equal sided quadrilateral with no right angles.
You can make a four sided shape with 3 right angles, but it must have another right angle, too. So technically, yes.
