Question

Check whether 3cm , 4cm, 5cm can be sides of triangle or not?​

Answer 1

Answer:

Yes they can be the sides of a triangle

Step-by-step explanation:

Yes they can be the sides of a triangle because sum of two smaller sides is greater than the third side. i.e 3+4>5

Answer 2

Answer:

Step-by-step explanation:

We know that sum of any two sides of a triangle is greater than the third side of the triangle.

Therefore, 3 cm+4 cm= 7 cm> 5 cm

4 cm + 5 cm = 9 cm > 3 cm

3 cm + 5 cm = 8 cm> 4 cm

Also, the difference of any two side lengths is less than the third side length.

Therefore, 4 cm-3 cm= 1 cm<5 cm

5 cm - 4cm = 1 cm< 3 cm

5 cm - 3 cm = 2 cm<4 cm

Since the sum of any two side is greater than the third side and the difference of any two sides is less than the third side, so the given side lengths will form a triangle.
