# Quadrilateral Flow Chart A flowchart illustrating the relationships between different types of quadrilaterals. **Polygon** * Closed figure with all sides * Composed of line segments * Sum of interior angles = 360° **Quadrilateral** **Trapezoid** * Exactly 1 pair of sides * Two right angles (connecting the parallel sides) - *Right Trapezoid* * Each pair of base angles are = - *Isosceles Trapezoid* * One pair of sides, the legs * (Not the parallel sides which are called the bases) **Parallelogram** * Opposite sides are parallel (II) & congruent * Opposite angles are = * Consecutive angles = 180° * Diagonals bisect each other * Each diagonal divides the quadrilateral into 2 triangles **Kite** * Exactly two distinct pairs of adjacent sides * Diagonals are perpendicular (1) * One diagonal divides the quadrilateral into 2 triangles **Rectangle** * All angles are right angles * Diagonals are = **Rhombus** * All sides are = * Diagonals are perpendicular (1) * Diagonals bisect opposite angles **Square** * All angles are right angles * All sides are = * Diagonals are = (perpendicular) * Diagonals bisect opposite angles **Isosceles Trapezoid** * Each pair of base angles are = * One pair of sides, the legs * (not the parallel sides which are called the bases)
