Quadrilateral Family Worksheets
What is the Quadrilateral Family? Polygons with four sides are known as the quadrilaterals. The sum of all the interior angles of a polygon is 360 degrees. Quadrilaterals are fundamentally broken into parallelograms and trapezoids. Parallelograms include square, rectangle, and rhombi, and trapezoid includes isosceles trapezoid. Apart from these two categories, a kite is also another common type of quadrilateral. Kite  Kite is the quadrilateral with two pairs of consecutive sides and noncongruent opposite sides. One of the pair of the opposite side is bisected by a diagonal. The diagonal of the kite is also noncongruent. Trapezoid  A trapezoid is a quadrilateral that has exactly one pair of parallel opposite sides. The legs of its angles are all supplementary. Isosceles trapezoid is a trapezoid that has congruent base angles and the legs of the angles are also congruent. Also, the diagonal of isosceles trapezoid is congruent. Parallelogram  A parallelogram is a quadrilateral that has two pairs of parallel sides with congruent, opposite angles and sides. Diagonals of a parallelogram bisect each other, and the consecutive angles are supplementary. Rhombus  A rhombus is a type of parallelogram that has four congruent sides and noncongruent diagonals. These diagonals bisect the pair of opposite angles and are perpendicular. Square  Square is the parallelogram that has four congruent angles and sides. The diagonals of a square are also congruent. Square exhibits all the properties of the rectangle and rhombus. Rectangle  A rectangle is a parallelogram with four congruent right angles and diagonals. The diagonal of a rectangle creates four isosceles triangles.

Basic Lesson
Trapezoid has only one set of parallel sides. (True or False) True because it is the property of trapezoid that it has one set of parallel side and other are non parallel.

Demonstrates the how to find various measures based on the properties of quadrilaterals. The perimeter of a square is 360. What is the area of the square? The square has 4 congruent sides, if The perimeter is 360, each side must be 360/4= 90. each side is 90 ,the area of square is base times height = 90 x 90 =8100.
