a triangular pyramid, i think
A rhombus has four sides and four corners (or vertices). All sides of a rhombus are of equal length, and opposite angles are equal. Additionally, the diagonals of a rhombus bisect each other at right angles.
Shapes that have only square corners, or right angles, include rectangles, squares, and certain types of polygons like right-angled trapezoids. These shapes are characterized by their 90-degree angles at each corner. In the case of polygons, all interior angles must be right angles for them to have square corners. Examples include a square, which has four equal sides and corners, and a rectangle, which has opposite sides equal and also features four right angles.
A shape with nine corners is called a nonagon. In geometry, a nonagon is a polygon that has nine sides and nine angles. It can be regular, where all sides and angles are equal, or irregular, where the sides and angles are not necessarily equal.
A rhombus has 4 equal sides with 2 acute and 2 obtuse interior angles whereas a rectangle has 2 pairs of equal sides of different lengths and 4 equal interior right angles
(1) Opposite sides are the same length and (2) All four corners are right-angles.

A square is a rectangle. A square is a rectangle with equal sides. A rectangle Has to have 4 right angles (and only 4 corners). A Square has the same definition (4 right angles, and only 4 corners) but all the sides have to be equal. A square is not a rhombus. A rhombus is a parallelogram with equal sides. A parallelogram has to have 4 sides (2 pairs of equal sides.) The equal sides must be parallel. A rhombus has the same definition (4 sides - 2 pairs of equal sides. The equal sides must be parallel.) but all the sides have to be equal lengths.
A square has four perpendicular sides.
A rhombus has 4 equal sides with 2 acute and 2 obtuse interior angles whereas a rectangle has 2 pairs of equal sides of different lengths and 4 equal interior right angles
(1) Opposite sides are the same length and (2) All four corners are right-angles.
Both statements are not always true. A square is a rectangle (a shape four sides and four corners which are all right angles) but a rectangle is not necessarily a square (a shape with four equal sides and four corners that are all right angles).
A QUADRILATERAL has four corners and four sides, along with four angles. These do not need to be congruent (equal) but they can be.
Rhombus has 4 equal sides and no right angles
You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.
