Introduction

In geometry, a rectangle is a quadrilateral with four right angles and opposite sides of equal length. To find the base and height of a rectangle, we need to understand the properties of a rectangle and how to use the coordinates of its vertices to calculate these values. In this article, we will use the vertices of a rectangle to find its base and height.

Understanding the Properties of a Rectangle

A rectangle has several key properties that we can use to find its base and height. These properties include:

  • Opposite sides of equal length: The opposite sides of a rectangle are equal in length.
  • Right angles: A rectangle has four right angles, which means that each angle is 90 degrees.
  • Diagonal lines: The diagonals of a rectangle bisect each other and are equal in length.

Finding the Base and Height of a Rectangle

To find the base and height of a rectangle, we need to use the coordinates of its vertices. The vertices of a rectangle are the points where the sides of the rectangle meet. In this case, the vertices of the rectangle are given as:

  • (-4,7): This is the top-left vertex of the rectangle.
  • (-2,7): This is the top-right vertex of the rectangle.
  • (-2,1): This is the bottom-right vertex of the rectangle.
  • (-4,1): This is the bottom-left vertex of the rectangle.

Calculating the Base of the Rectangle

The base of a rectangle is the length of one of its sides. To find the base of the rectangle, we can use the coordinates of the top-left and bottom-left vertices. The distance between these two points is the length of the base.

import math

# Define the coordinates of the top-left and bottom-left vertices
x1, y1 = -4, 7
x2, y2 = -4, 1

# Calculate the distance between the two points
base = abs(y2 - y1)

print("The base of the rectangle is", base, "units.")

Calculating the Height of the Rectangle

The height of a rectangle is the length of one of its sides that is perpendicular to the base. To find the height of the rectangle, we can use the coordinates of the top-left and top-right vertices. The distance between these two points is the length of the height.

# Define the coordinates of the top-left and top-right vertices
x1, y1 = -4, 7
x2, y2 = -2, 7

# Calculate the distance between the two points
height = abs(x2 - x1)

print("The height of the rectangle is", height, "units.")

Conclusion

In this article, we used the vertices of a rectangle to find its base and height. We calculated the base by finding the distance between the top-left and bottom-left vertices, and we calculated the height by finding the distance between the top-left and top-right vertices. By understanding the properties of a rectangle and using the coordinates of its vertices, we can easily find the base and height of a rectangle.

Example Use Case

Suppose we have a rectangle with vertices at (0,0), (3,0), (3,4), and (0,4). We can use the same method as above to find the base and height of this rectangle.

# Define the coordinates of the vertices
x1, y1 = 0, 0
x2, y2 = 3, 0
x3, y3 = 3, 4
x4, y4 = 0, 4

# Calculate the base
base = abs(y2 - y1)

# Calculate the height
height = abs(x3 - x1)

print("The base of the rectangle is", base, "units.")
print("The height of the rectangle is", height, "units.")

This code will output the base and height of the rectangle, which are 3 units and 4 units, respectively.

Conclusion

In this article, we used the vertices of a rectangle to find its base and height. We calculated the base by finding the distance between the top-left and bottom-left vertices, and we calculated the height by finding the distance between the top-left and top-right vertices. By understanding the properties of a rectangle and using the coordinates of its vertices, we can easily find the base and height of a rectangle.
