To find the area of a triangle using coordinate geometry, you can use this formula:

Area = ½ | x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂) |

Let’s break it down step by step:

1. Identify the points:

   • Name the spots where the corners of the triangle are. Call them (x₁, y₁), (x₂, y₂), and (x₃, y₃).

2. Plug in the coordinates:

   • Put the points you found into the formula.

3. Calculate:

   • When you do the math, you’ll find the area of the triangle. It’s really that simple!

From what I've seen, this way is super easy and shows how the points connect to form the triangle's area!
