### Kites

By: Bethany Walters, Autumn Walters, Josh Taylor, Connor Jaggers, David Berger

Kite: Has two pairs of equal sides. Each pair must be adjacent sides, and each pair must be distinct. Meaning the pairs cannot have a side in common.

Properties

Area and perimeter are also properties.

Diagonals intersect at right angles; meaning that they always dissect each other at 90 degrees.

Angles between unequal sides are equal

Where the red lines on the inside of the kite intersect they are crossing at 90 degrees, using the property diagonals intersect at right angles.

Area can be calculated by using the “diagonals” method. Once you know the lengths of the two diagonals, the area is half the product of the diagonals.

Area= d₁d₂

2

Finding the area of a kite is pretty easy. You use the method d₁ multiplied by d₂ then you divide it by 2.

d₁ is the length of one diagonal.

d₂ is the length of the other diagonal.

In this drawing:

d₁ would be 6

d₂ would be 10

When multiplying that you would get 60.

Then divide by two giving you the answer of 30 as your area.

10

Finding the perimeter is also easy. All you’re doing is finding the distance around the kite.

Perimeter= 2a+2b

13.5

13.5

When finding the perimeter you use the method 2a+2b.

2a is the length of each side in one pair.

2b is the length of each side in the other pair.

In this drawing:

2a= 13.5+13.5= 27

2b= 21.3+21.3= 42.6
