Easily calculate the area, perimeter, centroid, and midpoints of any triangle using its vertex coordinates. Our free online Triangle Vertices Calculator simplifies complex geometry, providing instant, accurate results for students, engineers, and designers.
Formula:
To calculate the area of a triangle given its three vertices (x1, y1), (x2, y2), and (x3, y3), we use the formula:
Area (A) = ½ |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|
The perimeter is the sum of the lengths of its three sides, and the centroid is the average of the coordinates.
