Kite, special member of Quadrilateral family

A quadrilateral is a four sided polygon. Therefore the total number of degrees of interior angles is 360° Hi, I am quadrilateral

A trapezoid is a quadrilateral with one pair of parallel lines. I am Trapezium

A parallelogram is quadrilateral bounded by f two pairs of parallel lines. I am parallelogram

A parallelogram is a quadrilateral whose opposite sides are parallel. Property: The opposite sides of a parallelogram are of equal length. A B C D

A B C D AB = CD and BC = AD

A B C D  A =  C and  B =  D Property: The opposite angles of a parallelogram are of equal measure.

A B C D  A +  B = 180 0 and  B +  C = 180 0 Property: The adjacent angles in a parallelogram are supplementary.

Hi, I am Rectangle

A B C D A rectangle is a parallelogram with four right angles. A rectangle is a parallelogram. Its opposite sides are congruent. It satisfies all other properties of parallelograms.

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 I am Rhombus

The diagonals of a rhombus are perpendicular bisectors of one another A BC D O

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.

Adjacent sides equal Adjacent sides equal and angles are 90 0 Angles are 90 0

Hi, I am Square A square has the properties of a rhombus and a rectangle. Its sides intersect at 90° and all four sides are congruent.

Kite Hi, I am Kite I am a special member of Quadrilateral family.

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.
