can a triangle have sides with lengths 8, 13, and 21. A- No; 8 + 13 13. C- Yes; The side lengths pass all three tests of the Triangle Inequality Theorem. D- No; 8 + 13 = 21 which is not greater than the third side length.

Question

can a triangle have sides with lengths 8, 13, and 21. A- No; 8 + 13 < 21, 13 + 21 < 8, and 8 + 21 < 13 B-Yes; 8 + 13 > 21, 13 + 21 > 8, and 8 + 21 > 13. C- Yes; The side lengths pass all three tests of the Triangle Inequality Theorem. D- No; 8 + 13 = 21 which is not greater than the third side length.
