प्रश्न
The lengths of two sides of a triangle are 12 cm and 15 cm. Between what two measures should the length of the third side fall?
उत्तर
In a triangle, the sum of the lengths of either two sides is always greater than the third side and also, the difference of the lengths of either two sides is always less than the third side. Here, the third side will be less than the sum of these two (i.e., 12 + 15 = 27) and also, it will be greater than the difference of these two (i.e., 15 − 12 = 3). Therefore, those two measures are 27cm and 3 cm.
