3 cm 3 cm 3cm so theres 3 for each side
1St set of sides will make a triangle because to construct a triangle sum of two side must be more than the 3rd one
13cm, 7cm, 6cm
To make a triangle you have to think about it in this way. The two smallest numbers should equal the largest number.
13 cm, 7 cm, 6 cm
The sum of the 2 shorter sides of the triangle has to be equal or longer than the longest side. In this case 7+6=13 which is equal.
10cm, 9cm, 9cm
Hope it helps:)
For a triangle to be formed, the sum of any two sides must be greater than or equal to the third side.13cm , 7cm , 6cm forms a degenerate triangle. (The sum of sides 7cm and 6cm is equal to the third side 13 cm)10cm , 9cm , 9cm form a triangle. (The sum of any two sides is greater than the third side)
