A convex quadrilateral with two pairs of adjacent congruent sides.


  • A kite belongs to several classes of quadrilaterals, including the class of quadrilaterals with symmetry and the class of convex quadrilaterals. For this reason, we can say that a kite is a quadrilateral that belongs to the class of convex quadrilaterals that have two pairs of adjacent congruent sides.
  • One of the diagonals of a kite is a line of symmetry; the other diagonal divides the figure into two isosceles triangles.
  • When a kite has only one line of symmetry (figure shown below on the right, for example), it is sometimes called an arrowhead.
  • The diagonals of a kite are perpendicular.
  • A kite with two lines of symmetry has four congruent sides; therefore, it belongs to the class of rhombuses.
