How to find the perimeter of a kite
Like any polygon, the perimeter is the total distance around the outside,
which can be found by adding together the length of each side.
For example, a kite whose sides are 4,4,10 and 10, the perimeter is the sum of these, or:
By definition, a kite has two pairs of equal sides. In the figure above AB=AD and BC=DC.
So, as a formula we can say:
where:
a is the length of each side in one pair
b is the length of each side in the other pair
In the figure above, drag any orange dot to resize the kite. From the side lengths shown, calculate the perimeter
and verify your result matches the formula at the top of the diagram.
