Study Notes
Properties of 2D Shapes
- A 2D shape with curves and not a polygon is a circle.
- Factors that can affect the properties of 2D shapes include size, shape, and angle measurements.
Polygons
- A regular polygon is a 2D shape with straight sides and all sides and angles equal.
- The main difference between a regular polygon and other common polygons is that regular polygons have all sides and angles equal, while other polygons do not.
Differences between 2D and 3D Shapes
- The main difference between 2D shapes and 3D shapes is that 2D shapes have straight sides or curves, while 3D shapes have volume and occupy space.
Examples of Shapes
- An example of a curved shape that is not a polygon is an ellipse.
- An example of a regular polygon is an equilateral triangle.
