Perimeter of a kite
Definition: The total distance around the outside of a kite
Try this Drag any orange dot to resize the kite. The perimeter is calculated as you drag.

## 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.

... I have a small favor to ask. Over the years we have used advertising to support the site so it can remain free for everyone. However, advertising revenue is falling and I have always hated the ads. So, would you go to Patreon and become a patron of the site? When we reach the goal I will remove all advertising from the site.

It only takes a minute and any amount would be greatly appreciated. Thank you for considering it!   – John Page
