Radial Symmetry Radial symmetry or balance is a type of balance in which the parts of an object or picture are regularly arranged and radiate from a central point. It appears both in natural and in human-made objects.
Three Types of Balance or Symmetry Radial Symmetry is only one of three types of balance. The others are Mirror or Bilateral Symmetry and Asymmetry .
Mirror or Bilateral Symmetry Also called reflectional or line symmetry , mirror or bilateral symmetry is a type of balance in which a center line, called the line of symmetry , divides an object in half so that one side mirrors the other.
Asymmetrical Balance In art, asymmetrical balance is a form of symmetry in which the two sides of a picture or object are different but are visually balanced. They are visually equal without being identical. Most modern art is asymmetrical. Starry Night by Vincent Van Gogh
Radial symmetry is found in both natural and human-made objects. Natural Objects
To create a radial symmetry design, begin by tracing a large circle on white drawing paper. Then, using a ruler, divide the circle in half, then into fourths. Draw a detailed line design in one "piece of the pie," then repeat it exactly the same way in the other “pieces.” Use colored pencils, markers, or paint to color each piece, again, exactly the same. The same idea also works with cut paper instead of drawing.
Divide any size circle by this method to create symmetrical, congruent shapes. Each of the final pieces are congruent shapes.
Use colored pencils, markers, or paint to color each piece exactly the same.
TEKS: Geometry and spatial reasoning. The student recognizes congruence and symmetry . The student is expected to: (A) identify congruent shapes; (B) create shapes with lines of symmetry using concrete models and technology; and (C) identify lines of symmetry in shapes.
