Answer:

We can have triangle with those sides.

Step-by-step explanation:

To check if some sides can be side lengths of triangle, every side must be less than sum of other two.

a=2.8

b=4.0

c=2.8

So, lets check.

a<b+c  2.8<6.8

b<a+c 4.0<5.6

c<a+b 2.8<6.8

We see that it is true. So 2.8;4.0 and 28 could be side lengths of triangle.

A triangle is a polygon with 3 sides.It is possible to make a triangle with sides of 2.8 cm, 4.0 cm, and 2.8 cm.

What is a triangle?

A triangle is a polygon with 3 sides. For a successful formation of the triangle, the sum of any two sides should be equal to the third side of the triangle.

For the formation of a triangle, the sum of any two sides of the triangle must be greater than the third side.

[tex]4+2.8 > 2.8\\\\2.8+2.8 > 4\\\\2.8+4 > 2.8\\\\[/tex]

Since the sum of any two sides combined is greater than the third side of the triangle. Therefore, it is possible to make a triangle with sides of 2.8 cm, 4.0 cm, and 2.8 cm.
