Example 3 - Chapter 6 Class 7 Triangle and its Properties - Teachoo
Is there a triangle whose sides have lengths 10.2 cm, 5.8 cm & 4.5 cm?
If these sides form a triangle, then
Sum of two sides > Third side
If two sides are
10.2, 5.8 , Sum = 16 cm, which is greater than third side 4.5 cm
5.8, 4.5 , Sum = 10.3 cm, which is greater than third side 10.2 cm
4.5, 10.2 , Sum = 14.7 cm, which is greater than third side 5.8 cm
Here,
Sum of two sides is greater than third side in all three cases
So, possible.
