### Example Question #1 : Geometry

Which of the following shapes is a kite?

Explanation:

A kite is a four-sided shape with straight sides that has two pairs of sides. Each pair of adjacent sides are equal in length. A square is also considered a kite.

### Example Question #11 : Area

What is the area of the following kite?

Explanation:

The formula for the area of a kite:

,

where  represents the length of one diagonal and  represents the length of the other diagonal.

Plugging in our values, we get:

### Example Question #1 : How To Find The Area Of A Kite

Two congruent equilateral triangles with sides of length  are connected so that they share a side. Each triangle has a height of . Express the area of the shape in terms of .

Explanation:

The shape being described is a rhombus with side lengths 1. Since they are equilateral triangles connected by one side, that side becomes the lesser diagonal, so .

The greater diagonal is twice the height of the equaliteral triangles, .

The area of a rhombus is half the product of the diagonals, so:

### Example Question #1 : How To Find The Area Of A Kite

The diagonals of a kite are  and . Find the area.

Explanation:

The formula for the area for a kite is

, where  and  are the lengths of the kite's two diagonals. We are given the length of these diagonals in the problem, so we can substitute them into the formula and solve for the area:
