Which of the following possibilities will form a triangle?


A. Side = 15 cm, side = 7 cm, side = 7 cm

B. Side = 15 cm, side = 7 cm, side = 9 cm

C. Side = 14 cm, side = 6 cm, side = 7 cm

D. Side = 14 cm, side = 6 cm, side = 8 cm

Respuesta :

We have this property of triangle:

sum of two sides > third side

Let us check for all options.

A.

7+7 >15

14>15

False

So option A is not correct.

B. 15, 7 , 9

15+7>9

22>9, true

7+9>15

16>15, true

15+9>7

24>7, true

So option B is correct.

C. 14, 6 ,7

14+6>7

20>7 , true

6+7>14

13>14, false

so option C is incorrect

D. 14, 6, 8

8+6 >14

14>14, false

So option D is incorrect.


Answer: B. Side = 15 cm, side = 7 cm, side = 9 cm

I took the test too! and got it right, so for sure you will get it right too.
