## Introduction to Geometric Shapes

- A geometric shape is a figure that is made up of straight lines and points. There are many different types of geometric shapes, including squares, circles, triangles, and hexagons.
- Each geometric shape has its own unique properties. For example, squares are always right angles, and circles have 360 degrees of rotation. Triangles are always three-sided, and hexagons always have six sides.
- Geometric shapes are often used in math and physics problems. For example, a physicist might use a circle to model the path of a planet in space. A mathematician might use a triangle to solve a geometry problem.
- Geometric shapes can also be used to create designs and patterns. Some famous geometric designs include the Möbius strip and the Sierpinski triangle.

## List of Geometric Shapes

There are many different types of geometric shapes. Some of the most common shapes are squares, circles, triangles, and rectangles. Each of these shapes has specific properties that make them unique. For example, squares are always right angles, circles have a defined radius, and triangles have three angles.

## Geometric Shapes Definition with Examples

- A geometric shape is a two-dimensional or three-dimensional object that has a specific shape and size. Geometric shapes can be classified as either primitive shapes or composite shapes.
- Primitive shapes are basic shapes that can be created by combining just a few lines or points. Composite shapes are shapes that are created by combining two or more primitive shapes.
- Some common primitive geometric shapes include circles, squares, rectangles, triangles, and hexagons. Some common composite geometric shapes include stars, crosses, and cubes.

## List of 2D & 3D Shapes

2D shapes:

- Square
- Rectangle
- Triangle
- Circle

3D shapes:

- Cone
- Sphere
- Cylinder
- Prism

## Difference between 2D Shapes & 3D Shapes

2D shapes are flat, while 3D shapes have depth. 3D shapes can be rotated in all directions to reveal different faces. 2D shapes can only be rotated along a single plane.

## Properties

The properties of a material determine how it behaves when it is subjected to a force or a temperature. The following is a list of some common material properties.

### 1.Density

The density of a material is the measure of how much mass is contained in a given volume. The higher the density of a material, the more mass is contained in a given volume.

### 2.Hardness

The hardness of a material is a measure of how resistant it is to indentation. The harder a material is, the more resistant it is to indentation.

### 3.Elasticity

The elasticity of a material is a measure of how much it will stretch when subjected to a force. The more elastic a material is, the more it will stretch when subjected to a force.

### 4.Thermal Conductivity

The thermal conductivity of a material is a measure of how well it conducts heat. The higher the thermal conductivity of a material, the better it conducts heat.

### 5.Thermal Expansion

The thermal expansion of a material is a measure of how much it will expand when subjected to a change in temperature. The higher the thermal expansion of a material, the more it will expand when subjected to a change in temperature.
