Question

Is it possible to draw a triangle,the length of whose sides are 7cm,8cm,15cm​

Answer 1

Answer:

yes

Step-by-step explanation:

7+8=15

15+15=draw a triangle

Answer 2

Answer:

No

Step-by-step explanation:

Reason:

One side of the triangle has to be less than the sum of the other two sides and greater than the magnitude of their difference.

i.e.,

Rule 1: (side1 + side2) > side3

Rule 2: Side3 < |side1 - side2|

Lets check the fact by adding / subtracting two sides and comparing with the third one..

Case1: 7+ 8 = 15 = length of third side. Rule1 fails

Case2:

8+15 > 7 Rule1 sucess

15–8 = 7 = length of third side. Rule 2 fails.

Case3:

7+15>8 Rule1 success

15–7=8 = length of third side. Rule 2 fails.

So, considering the rules and checking the facts..

t is impossible to create a triangle with above 3 sides.
