Classifying+Quadrilaterals


 * // Quadrilaterals //** There are a total of eight kind of polygons classified as a quadrilateral.

**// 4 right angles //**
 * // Square //**
 * // All angles and sides are congruent //**
 * // 2 sets of parallel lines //**
 * // Always parallelogram //**
 * // Only regular quadrilateral //**
 * // Rectangle //**
 * // 4 right angles //**
 * // 2 sets of parallel lines (opposite) //**
 * // 2 sets of congruent lines (opposite) //**
 * // Always Parallelogram //**
 * // Never kite //**

[|characteristics of a parallelogram]
 * // Parallelogram //**
 * // Consecutive angles=180degrees //**
 * // 2 sets of congruent sides //**
 * // Opposite sides are parallel and congruent //**
 * // Congruent opposite angles //**
 * // Diagonals bisect //**
 * // Sometimes square //**
 * // Sometimes rectangle //**


 * // Trapezoid //**
 * // 1 set of parallel lines //**
 * // Never parallelogram //**
 * // Parallel sides are called bases //**

characteristics of a rhombus Kite //**
 * // Rhombus //**
 * // 2 sets of parallel lines (opposite) //**
 * // Similar to parallelogram //**
 * // All sides are congruent //**
 * // Opposite congruent angles //**
 * // Sometimes a square //**
 * // Diagonals bisect and are perpendicular //**
 * // Always parallelogram //**
 * // [[image:http://thesaurus.maths.org/mmkb/media/png/Rhombus.png width="150" height="150"]]
 * // 2 sets of congruent adjacent sides //**
 * // No parallel lines //**
 * // Diagonals bisect and are perpendicular //**
 * // One set of opposite congruent angles //**
 * // 2 90degree angles //**
 * // 1 pair of opposite angles is congruent (ones that are between the sides of unequal length //**


 * // Isosceles Trapezoid //**
 * // 2 congruent lines (outside) //**
 * // One set of parallel lines //**
 * // Base angles are congruent //**
 * // Diagonals are congruent //**
 * // Opposite angles=180degrees //**


 * // Irregular Quadrilateral //**
 * // Does not have any special properties //**
