There are many types of quadrilaterals, but the main one is the rHomBus and some other one
All kites are quadrilaterals, but quadrilaterals are not kites.
All parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms
All quadrilaterals have 4 sides
All 4 sided parallelograms are quadrilaterals.
The 7 main types of quadrilaterals are the square, rectangle, rhombus, parallelogram, trapezium, kite and rhomboid.

7 quadrilaterals = 7 x 4 = 28 sides 8 hexagons = 8 x 6 = 48 sides Total is 76 sides
You're supposed to ask only one question at a time but here we go for 15 or more questions about quadrilaterals:- 1 Quadrilaterals are 4 sided 2 dimensional polygons 2 Quadrilaterals have 4 interior angles that add up to 360 degrees 3 Quadrilaterals have 4 exterior angles adding to 360 degrees 4 Quadrilaterals have 2 diagonals 5 Quadrilaterals have a perimeter which is the sum of their 4 sides 6 Quadrilaterals have areas with formulae depending on their types 7 Quadrilaterals can individually tessellate 8 Quadrilaterals can be split into 2 triangles 9 Quadrilaterals can be squares 10 Quadrilaterals can be rectangles 11 Quadrilaterals can be parallelograms 12 Quadrilaterals can be rhombuses 13 Quadrilaterals can be trapezoids or trapeziums 14 Quadrilaterals are sometimes isosceles trapezoids 15 Quadrilaterals can look like kites 16 Quadrilaterals can undergo transformations on the Cartesian plane 17 Quadrilaterals are congruent or similar when identical in angles and shapes 18 Quadrilaterals can form the cross-section of prisms 19 Quadrilaterals sometimes have lines of symmetry 20 Quadrilaterals have certain properties within a circle 21 Quadrilaterals can be subjected to trigonometry QED by David Gambell
A heptagon has seven sides and a quadrilateral has four, so 1 heptagon and 3 quadrilaterals have 1*7 + 3*4 = 7 + 12 = 19 sides altogether.
There are 7*4 + 8*6 = 28 + 48 = 76 sides.
Have a look at the picture I put into this other answer. It will show you the 7 quadralaterals. http://wiki.answers.com/Q/What_is_a_quadrilateral_where_each_angle_is_right_angle
All kites are quadrilaterals, but quadrilaterals are not kites.
All parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms
All squares are quadrilaterals. Not all quadrilaterals are squares.
what a quadrilaterals
All quadrilaterals are 4 sided shapes which includes trapezoids.
