Final answer:
The formula for the perimeter of a triangle is to add up the lengths of all three sides. If you only have one side of the triangle and it is on a graph, you can use the distance formula to find the lengths of the other sides.
Step-by-step explanation:
The formula for the perimeter of a triangle is to add up the lengths of all three sides. Let's say the lengths of the sides are a, b, and c. Then the perimeter is given by the formula:
Perimeter = a + b + c
If you only have one side of the triangle and it is on a graph, you can use the distance formula to find the lengths of the other sides. The distance formula is:
Distance = √((x2 - x1)^2 + (y2 - y1)^2)
By substituting the coordinates of the known side and the unknown side into the distance formula, you can calculate the lengths of the remaining sides.
