Two-dimensional (2D) shapes are flat figures that have length and width but no depth. Here are several examples of common 2D shapes:
1. **Circle** - A round shape with all points equidistant from the center.
2. **Square** - A shape with four equal-length sides and four right angles.
3. **Rectangle** - A shape with four sides where opposite sides are equal in length and all angles are right angles.
4. **Triangle** - A shape with three sides and three angles. Triangles can be categorized as equilateral (three equal sides and angles), isosceles (two equal sides and angles), or scalene (no equal sides or angles).
5. **Polygon** - A shape with three or more straight sides and angles. Specific examples of polygons include:
- **Pentagon** - Five-sided polygon with five angles.
- **Hexagon** - Six-sided polygon with six angles.
- **Heptagon** - Seven-sided polygon with seven angles.
- **Octagon** - Eight-sided polygon with eight angles.
6. **Ellipse** - A shape similar to a circle but elongated; it's a curve in a plane where the sum of the distances from two fixed points (foci) to every point on the curve is constant.
7. **Trapezoid (or Trapezium in UK English)** - A four-sided shape with at least one pair of parallel sides.
8. **Parallelogram** - A four-sided shape where the opposite sides are parallel and equal in length.
9. **Rhombus (or Diamond)** - A four-sided polygon (a type of parallelogram) where all sides have equal length.
10. **Oval** - A shape that looks like a squashed circle, technically a type of ellipse.
These are just a few examples of 2D shapes, and there are many more, especially when considering variations and subcategories of these basic forms.
