In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. … Kite quadrilaterals are named for the wind-blown, flying kites, which often have this shape and which are in turn named for a bird.
Why is a kite called a kite?
One technical definition is that a kite is “a collection of tether-coupled wing sets“. The name derives from its resemblance to a hovering bird. The lift that sustains the kite in flight is generated when air moves around the kite’s surface, producing low pressure above and high pressure below the wings.
What are the properties of a kite?
Kite properties include (1) two pairs of consecutive, congruent sides, (2) congruent non-vertex angles and (3) perpendicular diagonals. Other important polygon properties to be familiar with include trapezoid properties, parallelogram properties, rhombus properties, and rectangle and square properties.
Can a kite be concave?
Kites can be convex or concave. A dart is a concave kite. That means two of its sides move inward, toward the inside of the shape, and one of the four interior angles is greater than 180° .
Is a kite a triangle?
A kite is made up of two isosceles triangles joined base to base. Its diagonals are not equal but the longer one cuts the shorter in half at . The longer diagonal is a line of symmetry.

How do you prove a kite?
How to Prove that a Quadrilateral Is a Kite
- If two disjoint pairs of consecutive sides of a quadrilateral are congruent, then it’s a kite (reverse of the kite definition).
- If one of the diagonals of a quadrilateral is the perpendicular bisector of the other, then it’s a kite (converse of a property).
What are the five properties of kite?
- Opposite sides are parallel and equal in length.
- Opposite angles are equal in measure.
- Adjacent angles sum up to 180 degrees.
- It has 2 diagonals that bisect each other.
- Each diagonal divides the parallelogram into 2 congruent triangles.
What defines a kite?
In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. In contrast, a parallelogram also has two pairs of equal-length sides, but they are opposite to each other instead of being adjacent.
What does a kite equal up to?
By definition, a kite is a polygon with four total sides (quadrilateral). The sum of the interior angles of any quadrilateral must equal: degrees degrees degrees. Additionally, kites must have two sets of equivalent adjacent sides & one set of congruent opposite angles.
Why is a rhombus a kite?
A rhombus is a quadrilateral with all sides of equal length. So a rhombus does have two pairs of adjacent sides of equal length and is therefore a kite.
Can a kite have 2 right angles?
Thus the right kite is a convex quadrilateral and has two opposite right angles. If there are exactly two right angles, each must be between sides of different lengths. All right kites are bicentric quadrilaterals (quadrilaterals with both a circumcircle and an incircle), since all kites have an incircle.
Can a kite have parallel sides?
A kite has got two pairs of sides next to each other that have equal length. But none of the sides are parallel.
Does a kite have a right angle?
The intersection of the diagonals of a kite form 90 degree (right) angles. This means that they are perpendicular. The longer diagonal of a kite bisects the shorter one.
Are any Rhombi kites?
A kite has two sets of adjacent congruent sides. … This means that all Rhombi are kites, but not all kites are rhombi. A square is a rhombus with all right angles. This means that all squares are rhombi (which means they have to be kites), but not all rhombi are squares.
Why are all squares kites?
Most references list a square as a particular kind of kite which is equiangular (has all four angles equal). So a square is a kite, but a kite is not necessarily a square. False: A kite has only one pair of opposite angles congruent. A square has all angles congruent.
