Can These Three Numbers Be The Side Lengths Of A Triangle?

No

Step-by-step explanation: "Triangle Inequality theorem"

The sum of the two sides of a triangle must be greater than the third side.

2 + 10 = 12 meaning is not greater than the side 12.

In order to solve this, you should know this: the sum of the two shorter sides of the triangle should be greater than the longest side, or the hypotenuse.

a + b > c

The two smaller values, 10 and 2, could be a and b. 10 + 2 is 12, which is the hypotenuse, so these values cannot make up a triangle.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol
