If you draw one diagonal across a parallelogram, it will split it into two congruent triangles. A rectangle is a parallelogram, with all four angles equal to 90°.
The lateral sides are usually rectangles so each would comprise four right angles. However, the bases can be any pair of congruent triangles.
Any and all squares and rectangles. Every one of these two shapes has only right angles. Though some triangles also have right angles.
Yes. Rectangles have four right angles.
A rectangular prism is a hexahedron with six rectangular faces, each on which meets two others at right angles. In the special case that the rectangles are squares the shape is a cube so a cube is a special case of a rectangular prism.
squares, right triangles, rectangles
Examples of rectangular solids include shoeboxes, shipping boxes, and refrigerators. These objects have six faces that are rectangles, and all their edges are right angles.
The solid is a cuboid, or "right rectangular prism" in which all angles are right angles. It is a box shape, or regular hexahedron.

In fourth grade, students typically learn about shapes such as squares, rectangles, triangles, circles, and hexagons, as well as concepts like area, perimeter, and angles. They may also explore three-dimensional shapes such as cubes, cylinders, and spheres.
Squares, rectangles, and some triangles, most commonly. Any polygon could have a right angle if it is irregular.
Any and all squares and rectangles. Every one of these two shapes has only right angles. Though some triangles also have right angles.
No, circles do not have angles.
Yes. Rectangles have four right angles.
Regular shapes have equal sides and angles, like squares and equilateral triangles. Irregular shapes have sides and angles of varying lengths and measurements, like rectangles and scalene triangles. Regular shapes are typically easier to calculate and work with compared to irregular shapes.
