A triangle has three side lengths: 5 cm, 8 cm, and 15 cm. Can
these three lengths form a triangle?

Yes — all three lengths are positive.

No — the sum of the two shorter sides (5 + 8 = 13) is less than the longest side (15).

Yes — 5 + 15 = 20 > 8, so the triangle inequality is satisfied.

No — no two sides are equal, so the triangle can't close.
