Formula Used in “Area of Triangle with Coordinates Calculator”
The area of a triangle formed by three coordinates in a Cartesian plane can be computed using the following standard formula:
Area</, A = frac{1}{2} left| x_1(y_2 – y_3) + x_2(y_3 – y_1) + x_3(y_1 – y_2) right|
Step-by-Step Breakdown of the Formula
In the formula, each variable is defined as follows:
- x1: The x-coordinate of the first vertex of the triangle.
- y1: The y-coordinate of the first vertex of the triangle.
- x2: The x-coordinate of the second vertex of the triangle.
- y2: The y-coordinate of the second vertex of the triangle.
- x3: The x-coordinate of the third vertex of the triangle.
- y3: The y-coordinate of the third vertex of the triangle.
Calculation Process
To calculate the area of the triangle using the aforementioned formula, follow these steps:
- Identify the coordinates of the three vertices of the triangle (e.g., A(x1, y1), B(x2, y2), C(x3, y3)).
- Plug in the coordinates into the area formula.
- Perform the multiplication and subtraction within the absolute value brackets.
- Take the absolute value of the result.
- Divide the absolute value by 2 to obtain the area of the triangle.
Example Calculation
Let’s illustrate how to use the formula with a real-world example. Consider a triangle with vertices at the following coordinates:
- A(1, 2)
- B(4, 5)
- C(6, 1)
Inputs and Outputs
| Vertex | X Coordinate | Y Coordinate |
|---|---|---|
| A | 1 | 2 |
| B | 4 | 5 |
| C | 6 | 1 |
Substituting the coordinates into the formula, we have:
A = frac{1}{2} left| 1(5 – 1) + 4(1 – 2) + 6(2 – 5) right|
Calculating step by step:
- 1(5 – 1) = 4
- 4(1 – 2) = -4
- 6(2 – 5) = -18
Now, combining these values:
A = frac{1}{2} left| 4 – 4 – 18 right| = frac{1}{2} left| -18 right| = frac{1}{2} times 18 = 9
The area of the triangle with vertices A(1, 2), B(4, 5), and C(6, 1) is 9 square units.
