8-94. Imagine now that three possible measures for a triangle’s six parts (3 angles or 3 side lengths) are given. Do you think that everyone will make the same triangle in that case?
Investigate this question for three possible side lengths given.
- 1.5 cm, 5 cm, and 4.5 cm.
- 4.5 cm, 5 cm, and 7 cm.
- 1.5 cm, 4.5 cm, and 7 cm.
