A triangle has two sides with the lengths 8m and 15 m. Which of the following lengths could represent the length of the third side? Choose all that apply. 1. 23m 2. 4m 3. 10m 4. 14m 5. 7m

Answer 1

3. 10m

4. 14m

Angle inequality rule: A triangle can only form if it's 2 shortest sides add up to have MORE length than it's longer side.

1. 23 m

2. 4m

3. 10m

4. 14m

5. 7m

1 doesn't follow the angle inequality rule.
