<P>PROBLEM TO BE SOLVED: To solve the problems of being hard to understand because only the numerals and lines drawn in a figure on paper are written in learning the figures and angles, although it is mostly difficult for the children to divide a cake or a pizza equally when taking the cake or the pizza at a general home in the past. Ž<P>SOLUTION: In order to divide a round material (a circle) into parts of the same size, the angle of a circle should be known, so the way of dividing the angle of a circle and the circle is learnt using a picture figure table. Parts of various shapes are divided, combined and overlapped for easier understanding of the dividing way. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
