Answer:

2

Step-by-step explanation:

They have to connect. The triangles name would be: triangle 123

The third side may be 2 because 2 is between 1 and 3

The sides of the triangles are given as:

Lengths = 1 and 2

To determine the third length, we make use of the following triangle inequality theorem

x  + y > z

x  + z > y

y + z > x

So, we have:

1 + 2 > z

1 + z > 2

2 + z > 1

Solve for z in the inequalities

z < 3

z > 1

z > -1

Remove the negative value

z < 3

z > 1

This means that the value of z is between 1 and 3

Hence, the third side may be 2 because 2 is between 1 and 3
