Question

Does 7, 8, 20 forms a triangle

Ill give 50 points

Answer 1

No.

Because the sum of two lengths of a triangle must be greater than the longest length.

7 + 8 = 15

15 < 20

15 should be larger than the other side if it was to make a triangle. But because the side is larger than 20 it isn’t.

Answer 2

No

Explanation:

you can use the triangle inequality theorem which states that the sum of any two sides must be greater than the third side

7+8 is not greater than 20
