SYMMETRY WELL BALANCED ARRANGEMENT OF PARTS
back Line Symmetry EXIST WHEN TWO HALVES OF A FIGIURE CAN BE MADE TO MATCH BY FOLDING ON A LINE C VERTICAL HORIZONTAL
ROTATIONAL SYMMETRY back EXIST WHEN A FIGURE CAN BE ROTATED LESS THAN 360 0 ABOUT A CENTRAL POINT CALLED THE POINT OF ROTATION
square pentagon hexagon Regular Polygons HaveRotational and Line Symmetry triangle octagon
What symmetry do the following polygons have? • Square • Rectangle • Pentagon • Hexagon • Octagon RotationalSymmetry 1/3 or 120 0 symmetry 90, 180, 72, 60, 45 Equilateral triangle
Symmetry Is all around us cut an apple in half and you will find Rotational Symmetry
Symmetry is found in nature, just look around… • Snow Flakes • Insects • Plants and flowers • Animals • Sea Life • Can you think of more….
Lets Review . . .Click on link to return to page Line symmetry Rotational symmetry A For more review click on the image • Which letters of the alphabet have • horizontal symmetry? • vertical line symmetry? • rotational symmetry • Does the font you use make a difference? Print your full name in capital letters, what kind of symmetry can you find?
Your assignment….. You will design a quilt using a variety of rotational symmetric designs. You may use images from the internet or clip art. Created with a compass
