2 Dimensional Shapes Drawing - A Guide to Understanding and Creating Shapes

Introduction

---------

In geometry, two-dimensional (2D) shapes are flat shapes that have no thickness or depth. They can be drawn using various tools such as pencils, pens, and computers. In this article, we will explore the basics of 2D shape drawing and learn how to create different types of shapes.

Understanding Trigonometry

----------------------

Trigonometry is a branch of mathematics that deals with the relationships between side lengths and angles of triangles. It is an essential tool for creating 2D shapes as it helps us understand how to calculate the length of sides and angles of a triangle. There are three basic trigonometric functions: sine, cosine, and tangent.

The sine of an angle is equal to the length of the opposite side divided by the length of the hypotenuse (SOH). The cosine equals adjacent over hypotenuse (CAH), and tangent is equal to opposite over adjacent (TOA).

Types of 2D Shapes

----------------

There are various types of 2D shapes, including polygons, circles, and curves. Polygons are two-dimensional shapes that are formed by connecting straight line segments.

Creating 2D Shapes using Code

--------------------------

In computer programming, we can use code to create 2D shapes. Python is a popular programming language used for creating visualizations. Here's an example of how to draw a square and triangle using Python:

```

import matplotlib.pyplot as plt

fig, ax1 = plt.subplots(1, 1, figsize=(10, 9), facecolor=plt.get_cmap('viridis')(0.5))

ax1.set_title(f'Elephant', fontsize=14, pad=20)

elephant = '(3, 4), (4, 3), (2, 4), (1, 3)'

plot_polygon(ax1, *elephant)

plt.show()

publish_png_image(fig, 'draw-square-triangle.png')

```

In conclusion, 2D shape drawing is an important aspect of geometry and computer programming. Understanding trigonometry and the basics of shape creation can help us create complex shapes using code. Whether you're a student or a professional, learning about 2D shapes can be a fun and rewarding experience.
