Let's do this question the length of two sides of a triangle are seven and nine centimeter.
The length of the third side may lie between both the video.
Give it a try and then let's do it together.
All right.
We know that if A, B and C are three sides of a triangle, then A minus B has to be less than C and
C has to be less than A plus B, right.
So let's try that over here.
We have two sides, seven and nine.
So nine minus seven has to be less than the third side and the third side has to be less than nine plus
seven.
So that means two centimeters, less than the third side, less than 16 centimeters.
That gives us our answer, which is option C.
And remember, the third side cannot be two or 16, right?
It can be three or extra up to 15.
