Chapter 6: Quadrilaterals

- In this chapter we will study the characteristics and properties of 6 different kinds of quadrilaterals:
- Parallelograms
- Trapezoids
- Rectangles
- Rhombi
- Squares
- Kites
We will explore the essential characteristics of each of these shapes and use these characteristics to solve problems

- Interior Angles of any polygon follow the formula: 180(n-2) where “n” is the number of sides the polygon has.
- The exterior angles of any polygon always add to 360

- Rhombus: a parallelogram with 4 congruent sides, perpendicular diagonals, diagonals bisect opposite angles
- Rectangle: a parallelogram with 4 right angles and congruent diagonals
- Square: a parallelogram with 4 congruent sides and 4 right angles, perpendicular diagonals, diagonals bisect opposite angles

- Trapezoid has 2 bases and 2 legs. If the legs are equal then the trapezoid is an isosceles trapezoid
- The Midsegment of a trapezoid is parallel to and in between the bases. It follows the formula MS= ½(b1+b2)
- Isosceles Trapezoid: 2 equal legs, equal diagonals
- Kite: 2 pairs of = sides, diagonals are perpendicular
