Any triangle that is not a right angle triangle
Depending on the definition that is used, a trapezium is either a figure with four sides that has no parallel sides (American) or a figure with fours sides that has two parallel sides (British). Either way, a trapezium can not have 3 right angles.
A square, rectangle, or quadrilateral

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.

The 3 names for this figure are: 1. Square - all sides are parallel, there are 4 right angles, and all the sides are the same length. All squares are quadrilaterals and parallelograms. 2. Quadrilateral - 4 sides. NOT all quadrilaterals are squares, however. 3. Parallelogram - all sides are parallel. NOT all parallelograms are squares, however.
Yes and no. By definition, a quadrilateral is a closed figure with 4 sides. So any square or rectangle will answer your question. However a polygon with 4 sides which are unequal in length will not have 3 right angles.
-- it's a closed, plane figure -- it has 3 sides, 3 vertices, 3 interior angles (any one of these 3 statements implies the other 2) -- the sum of its interior angles is 180 degrees
A triangle.
A triangle has 3 sides and 3 interior angles that add up to 180 degrees.

A rhombus has four congruent sides. The angles don't matter, but if they're right angles, then the rhombus is a square.
A figure with four right angles is called a rectangle. A specific type of rectangle in which all the sides are of equal length is called a square.
