Can you construct a triangle that has side lengths 11 cm, 12 cm, and 15 cm?

To make a triangle the sum of two sides should be always more than side of the third side

1) 11+12 >15, 23 > 15, true

2) 11+15>12, 26>12, true

3) 12+15>11, 27>11, true

so yes, you can construct a triangle that has these lengths of the sides
