Step 1 : Take a chart and cut it like a triangle as shown in Fig. (a). Step 2 : Then fold it along the symmetric line AD. Then C and B will be one upon the other. Step 3 : Similarly fold it along CE, then B and A will be one upon the other. Step 4 : Similarly fold it along BF, then A and C will be one upon the other.Find AB, AC, BD, DC using a scale. Find (AB)/(AC), (BD)/(DC) check if they are equal ? In the three cases, the internal bisector of an angle of a triangle divides the opposite side internally in the ratio of the corresponding sides containing the angle. What do you conclude from this activity ? |
