Distance Formula Worksheet: Master Your Math Skills!
Table of Contents :
To master your math skills, especially in geometry and algebra, understanding the Distance Formula is essential. This formula allows you to calculate the distance between two points on a coordinate plane, making it a vital tool for students and professionals alike. In this article, we will delve into the Distance Formula, provide worksheets for practice, and explore various applications and tips to enhance your skills in using this formula effectively.
Understanding the Distance Formula
The Distance Formula is derived from the Pythagorean Theorem, which relates the lengths of the sides of a right triangle. The formula to find the distance (d) between two points ((x_1, y_1)) and ((x_2, y_2)) in a two-dimensional plane is expressed as:
[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ]
Breaking Down the Formula
- (x_1, y_1): Coordinates of the first point.
- (x_2, y_2): Coordinates of the second point.
- (\sqrt{}): Denotes the square root, which is necessary to ensure the distance is non-negative.
Important Note: "The Distance Formula is applicable in any dimension, but this explanation focuses on two-dimensional space for clarity."
Practical Examples
To solidify your understanding, let's walk through a couple of examples using the Distance Formula.
Example 1
Find the distance between points A(3, 4) and B(7, 1).
-
Identify the coordinates:
((x_1, y_1) = (3, 4)) and ((x_2, y_2) = (7, 1)) -
Substitute into the formula:
[ d = \sqrt{(7 - 3)^2 + (1 - 4)^2} ] -
Calculate:
[ d = \sqrt{(4)^2 + (-3)^2} = \sqrt{16 + 9} = \sqrt{25} = 5 ]
So, the distance (d) is 5 units.
Example 2
Find the distance between points C(-2, 3) and D(3, -2).
-
Identify the coordinates:
((x_1, y_1) = (-2, 3)) and ((x_2, y_2) = (3, -2)) -
Substitute into the formula:
[ d = \sqrt{(3 - (-2))^2 + (-2 - 3)^2} ] -
Calculate:
[ d = \sqrt{(5)^2 + (-5)^2} = \sqrt{25 + 25} = \sqrt{50} \approx 7.07 ]
The distance (d) is approximately 7.07 units.
Practice Worksheet
To help you master the Distance Formula, here’s a simple worksheet format you can use to practice. For each pair of points, calculate the distance.
<table> <tr> <th>Point 1 (x1, y1)</th> <th>Point 2 (x2, y2)</th> <th>Distance (d)</th> </tr> <tr> <td>(1, 2)</td> <td>(4, 6)</td> <td></td> </tr> <tr> <td>(-3, -5)</td> <td>(2, 1)</td> <td></td> </tr> <tr> <td>(0, 0)</td> <td>(5, 5)</td> <td></td> </tr> <tr> <td>(-1, 4)</td> <td>(3, -1)</td> <td></td> </tr> </table>
