Question

Tell whether or not the measurements below form a triangle:

1. 4, 5, 10

2. 12, 26, 20

3. 2, 3, 5

Answer 1

Explanation:

1 . 4,5,10 : this measurement does not form a triangle because the sum of two sides is not greater than the third side (longest side)

4 + 5 > 10

9 > 10 (this is not satisfied)

2. 12,26,20 :this measurement forms a triangle beacuse the sum of two sides is greater than the third side

12 + 26 > 20

38 > 20

3 .

2,3,4 : this measurement does not form a triangle because the sum of two sides is not greater than the third side.

2 + 3 > 5

5 > 5 (this is not satisfied)

Answer 2

Below.

Explanation:

If the sum of any 2 sides are less than or equal to the third side then there's no triangle

1. N0 because 4 + 5 < 10

2. YES

3. NO because 2 + 3 = 5.
