Family of quadrilaterals

  1. 1. Kite , special member of Quadrilateral family
  2. 2. Family of Quadrilaterals
  3. 3. A quadrilateral is a four sided polygon. Therefore the total number of degrees of interior angles is 360°
  4. 4. A trapezoid is a quadrilateral with one pair of parallel lines.
  5. 5. A parallelogram is quadrilateral comprised of two pairs of parallel lines.
  6. 6. A rectangle is a parallelogram with four right angles. A rectangle is a parallelogram, its opposite sides must be congruent and it must satisfy all other properties of parallelograms .
  7. 7. A rhombus is a type of parallelogram, and what distinguishes its shape is that all four of its sides are congruent. There are several formulas for the rhombus that have
  8. 8. A rhombus is a type of parallelogram, and what distinguishes its shape is that all four of its sides are congruent. Properties of the rhombus: 1. all four sides are congruent 2. Diagonals bisects each other 3. Diagonals are perpendicular A square is a rhombus and a rectangle. In other words, if each angle of a rhombus is 90°, then it's a square.
  9. 9. A square has the properties of a rhombus and a rectangle. Its sides intersect at 90° and all four sides are congruent.
  10. 10. Kite Who are you? Do you belong to family of Quadrilaterals?
  11. 11. Kite is a quadrilateral: * has two pairs of sides. * each pair is adjacent sides (they meet) that are equal in length. Also, the angles are equal where the pairs meet. Diagonals meet at a right angle, and one of the diagonal bisects (cuts equally in half) the other.
