If angle i is congruent to angle k find the perimeter of triangle jik

Like any polygon, the perimeter is the total distance around the outside, which can be found by adding together the length of each side. Or as a formula:Perimeter=a+b+cwhere:

a, b and c are the lengths of each side of the triangle

In the figure above, drag any orange dot to resize the triangle. From the side lengths shown, calculate the perimeter and verify your result matches the formula at the top of the diagram
