Activities
- Can you have a triangle with side lengths of 3, 5, and 7?
- Can you have a triangle that has side lengths of 2, 8, and 12?
- Explain why you can have a triangle that has side lengths of 5, 9, and 12.
- If you know that two sides of a triangle are equal to 6 and 10, explain how to find what the other side length must be.
- Suppose you have a triangle that has a perimeter of 12, list all the possible side lengths in the chart below.
- You have a triangle that has the side lengths of 7 and 10. Find the missing third side and tell whether the perimeter in the table is possible.
Answer Key/Rubric
- Yes
- No
- Student work might include, but is not limited to
- The sum of any two sides on the triangle is greater than the remaining third side
- 5 + 9 > 12
- 9 + 12 > 5
- 12 + 5 > 9
- This missing side has to be a number that is greater than 16. Student work might include, but is not limited to
- The third side must be a value greater than the sum of the two given sides.
- 10 + 6 = 16
- The last side must be greater than 16, not including the value 16.
