QUESTION: 1

In ΔABC, AB = 2.5 cm and BC = 6 cm. Then, the length of AC cannot be

Solution:

in triangle ABC

AB = 2.5 cm

BC = 6 cm

AC = ?

in any triangle sum of two sides > third side

=> AB + BC > AC

=> 2.5 + 6 > AC

=> AC < 8.5

AB + AC > BC

=> 2.5 + AC > 6

=> AC > 3.5

BC + AC > AB

=> 6 + AC > 2.5

=> AC > -3.5

Taking all together

3.5 < AC < 8.5

3.6 , 3.8 & 4 lies betwenn them

but not 3.4

Hence Length of AC can not be 3.4 cm
