You got it! Here are explanations and examples for those words, focusing on their geometric properties:

Triangle

A triangle is a polygon with three sides and three angles.

• An equilateral triangle has three equal sides and three equal angles.
• A right triangle has one angle that is 90 degrees.
• Triangles are used in many structures, such as bridges and roofs.

Cross

A cross is a geometric shape formed by two intersecting lines.

• The Christian symbol is a cross.
• The cross is also used as a symbol for direction or orientation.
• A cross can be used to mark a location on a map.

Pyramid

A pyramid is a polyhedron with a base that is a polygon and triangular faces that meet at a point called the apex.

• The Great Pyramid of Giza is a famous example of a pyramid.
• A square pyramid has a square base.
• Pyramids are often used in architecture and design.

Square

A square is a quadrilateral with four equal sides and four right angles.

• A square is a special type of rectangle.
• A square is also a special type of rhombus.
• Squares are commonly used in geometry and design.

Rectangle

A rectangle is a quadrilateral with four right angles.

• The opposite sides of a rectangle are parallel and equal in length.
• A square is a special type of rectangle with all sides equal.
• Rectangles are used in many everyday objects, such as doors, windows, and tables.

Circle

A circle is a closed curve that is perfectly round, all points on the curve being the same distance from the center.

• The artist drew a perfect circle on the canvas.
• The children formed a circle around the teacher.
• The path of the planets around the sun is not a perfect circle but an ellipse.

Cube

A cube is a three-dimensional solid with six square faces.

• A cube has 12 edges and 8 vertices.
• A cube is a special type of rectangular prism with all sides equal.
• Cubes are often used in geometry and design.

Sphere

A sphere is a three-dimensional solid that is perfectly round, all points on the surface being the same distance from the center.

• The Earth is approximately a sphere.
• A sphere has no edges or vertices.
• Spheres are often used in geometry and design.

Cylinder

A cylinder is a three-dimensional solid with two parallel circular bases and a curved surface connecting them.

• A can of soup is a cylinder.
• A cylinder has no vertices.
• Cylinders are often used in engineering and design.

Cone

A cone is a three-dimensional solid with a circular base and a pointed apex.

• An ice cream cone is a cone.
• A cone has one vertex and a curved surface.
• Cones are often used in geometry and design.

Quadratic Prism

A quadratic prism is a prism with a quadrilateral base and rectangular sides.

• A rectangular prism is a special type of quadratic prism with all sides rectangular.
• A cube is a special type of quadratic prism with all sides square.
• Quadratic prisms are often used in architecture and engineering.

Rhombus

A rhombus is a quadrilateral with four equal sides.

• A square is a special type of rhombus with all angles right angles.
• A rhombus is a special type of parallelogram with all sides equal.
• Rhombi are often used in geometry and design.

Triangular Prism

A triangular prism is a prism with a triangular base and rectangular sides.

• A triangular prism has five faces, nine edges, and six vertices.
• Triangular prisms are often used in architecture and engineering.

Two-dimensional shapes:

• Polygons: closed figures with straight sides, such as triangles, squares, and rectangles.
• Circles: closed figures with curved sides, such as a tire or a coin.
• Ellipses: closed figures with oval sides, such as an egg or a football.

• Three-dimensional shapes:
  • Polyhedra: solid figures with flat faces, such as cubes, pyramids, and prisms.
  • Spheres: solid figures with curved sides, such as a ball or a globe.
  • Cylinders: solid figures with curved sides and flat ends, such as a soda can or a tree trunk.
  • Cones: solid figures with curved sides that taper to a point, such as an ice cream cone or a volcano.

These are just a few of the many possible shapes. Many other shapes can be found in nature, art, and engineering.

Here are some other types of shapes:

• Star shapes: have multiple points that radiate from a central point, such as a starfish or a snowflake.
• Fractal shapes: have self-similar patterns that repeat at smaller and smaller scales, such as a fern or a cauliflower.
• Parametric shapes: are defined by mathematical equations, such as a helix or a parabola.
• Organic shapes: are found in nature, such as the shape of a leaf or a flower.
• Abstract shapes: are not based on any natural or mathematical form, such as the shapes found in art or design.

The possibilities are endless!
