What is a kite in geometry?

A kite is a quadrilateral that has two pairs of consecutive sides that are equal in length. The two pairs share no sides — one pair meets at the top vertex and the other pair meets at the bottom vertex.

What is the formula for the perimeter of a kite?

P = 2(a + b), where a is the length of one pair of equal sides and b is the length of the other pair. Since each value appears twice, you multiply their sum by 2.

Does the unit matter?

No — use any consistent unit (cm, m, inches, feet, etc.). The perimeter will be expressed in the same unit as your input.

What happens when a equals b?

When both side pairs are equal, the kite becomes a rhombus, and the perimeter simplifies to P = 4a.

Can a kite have a pair of equal opposite angles?

Yes. A kite always has one pair of equal opposite angles — the angles between the unequal sides. This is a standard geometric property of kites.

Is a square a special kite?

Yes. A square is both a rhombus and a kite where a = b and all angles are 90 degrees.
