Geometry Kites
A kite is a member of the quadrilateral family, and while easy to understand visually, is a little tricky to define in precise mathematical terms. A
A kite is a convex quadrilateral with two adjacent sides the same length and the other two adjacent sides the same length.

Things I know about kites… 1. 4 sides and 4 angles 4 2. the sum of the interior angle is 360 and the sum of the exterior 116 D angles is 360
3. Two pairs of adjacent sides of a kite are equal in length 4. One pair of opposite angles (the ones that are between the sides of unequal length) are congruent

5. One diagonal bisects the other. They do not bisect each other, however 6. The longer diagonal bisects a pair of opposite angles 7. Diagonals are perpendicular 8. One diagonal divides a kite into two isosceles triangles; the other (the axis of symmetry) divides the kite into two congruent triangles
