**2D Shapes and Their Properties Worksheets: A Comprehensive Guide**

**Introduction**

Understanding 2D shapes and their properties is an essential part of mathematics education for students of all ages. 2D shapes are geometric shapes that exist in two dimensions, having length and width but no thickness. Knowing the properties of these shapes is crucial for problem-solving and critical thinking. In this article, we will explore the different types of 2D shapes, their properties, and provide you with a range of worksheets to help your students master these concepts.

**Types of 2D Shapes**

### Rectangles

- A rectangle is a quadrilateral with four right angles (90°) and opposite sides of equal length.
- Properties: opposite sides are equal, all angles are right angles (90°).

### Squares

- A square is a special type of rectangle with all sides of equal length.
- Properties: all sides are equal, all angles are right angles (90°).

### Triangles

- A triangle is a polygon with three sides and three vertices.
- Properties: sum of interior angles is 180°, angles can be acute (less than 90°), right (90°), or obtuse (more than 90°).

### Circles

- A circle is a set of points equidistant from a central point (called the center).
- Properties: all points on the circle are equidistant from the center, the distance around the circle is called the circumference.

### Hexagons

- A hexagon is a polygon with six sides and six vertices.
- Properties: sum of interior angles is 720°, alternate angles are equal.

**Properties of 2D Shapes**

**Angles**: The sum of interior angles of a polygon is always (n-2) x 180°, where n is the number of sides.**Symmetry**: A shape has line symmetry if it looks the same on both sides of a line.**Perimeter**: The distance around a shape is called its perimeter.**Area**: The amount of space inside a shape is called its area.
