Perpendicular

GoMim AI | What is perpendicular and How to Calculate it

Introduction

In the world of mathematics, the concept of perpendicularity plays a crucial role in various fields such as geometry, trigonometry, and even in real-world applications like construction and design. Understanding what perpendicular means and how to calculate it can greatly enhance your problem-solving skills and mathematical comprehension. This article will delve into the definition and significance of perpendicular lines, and offer a step-by-step guide on how to determine perpendicularity using both traditional methods and modern AI tools.

What is it?

Perpendicular refers to the relationship between two lines which meet at a right angle, i.e., 90 degrees. In more technical terms, two lines are perpendicular if the product of their slopes is -1. Mathematically, if we have two lines with slopes $$m_1$$ and $$m_2$$, the lines are perpendicular if: $$m_1 \times m_2 = -1$$ For example, if one line has a slope of 2, a line perpendicular to it will have a slope of -1/2.

Why is it important?

Perpendicular lines are fundamental in various areas of mathematics and its applications. In geometry, they are used to define orthogonality and construct shapes with right angles, such as rectangles and squares. In trigonometry, understanding perpendicular lines can help in solving problems involving right-angled triangles. In real-world scenarios, perpendicular lines are crucial in engineering and architecture, ensuring that structures are level and stable. Additionally, perpendicularity is used in data analysis and computer graphics to calculate angles and distances accurately.

How to Calculate it Step-by-Step

To calculate whether two lines are perpendicular, follow these steps:


1. Identify the slopes of the lines.

- For line 1 with equation $$y = m_1x + c_1$$, identify the slope $$m_1$$.

- For line 2 with equation $$y = m_2x + c_2$$, identify the slope $$m_2$$.


2. Calculate the product of the slopes.

- Multiply the slopes: $$m_1 \times m_2$$.


3. Check the condition for perpendicularity.

- If the product is -1, the lines are perpendicular.


Example:


Let's determine if the lines $$y = 2x + 3$$ and $$y = -\frac{1}{2}x + 1$$ are perpendicular.


- Step 1: Identify the slopes: $$m_1 = 2$$ and $$m_2 = -\frac{1}{2}$$.

- Step 2: Calculate the product: $$2 \times -\frac{1}{2} = -1$$.

- Step 3: Since the product is -1, the lines are perpendicular.

Related Practice Problem

Problem: Given the two lines with equations $$y = 3x + 1$$ and $$y = -\frac{1}{3}x - 5$$, determine if they are perpendicular.

Step-by-step Solution:


  1. Identify the slopes of the lines.
  2. For the first line, $$y = 3x + 1$$, the slope $$m_1 = 3$$.
  3. For the second line, $$y = -\frac{1}{3}x - 5$$, the slope $$m_2 = -\frac{1}{3}$$.
  4. Calculate the product of the slopes.
  5. $$m_1 \times m_2 = 3 \times -\frac{1}{3} = -$$.
  6. Check the condition for perpendicularity.
  7. Since the product is -1, the lines are perpendicular.
