Final answer:
To calculate the length of AC in triangle ABC, use the distance formula by plugging in the coordinates of points A and C.
Step-by-step explanation:
To calculate the length of AC, we first need to know the coordinates of points A and C. Let's assume that point A has coordinates (x1, y1) and point C has coordinates (x2, y2).
The distance between two points can be calculated using the distance formula: √((x2 - x1)^2 + (y2 - y1)^2). So, to find the length of AC, plug in the coordinates of points A and C into the formula.
The length of AC represents the distance between points A and C in the triangle ABC. It is one of the sides of the triangle.
