FLASHCARD QUESTION
Front
What is the Triangle Inequality Theorem?
Back
The Triangle Inequality Theorem states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
2.
FLASHCARD QUESTION
Front
Which side lengths would NOT form a triangle? {3,4,5}, {2,5,9}, {5,10,12}, {7,9,11}
Back
{2,5,9} because 2 + 5 is not greater than 9.
3.
FLASHCARD QUESTION
Front
Can the following side measures form a triangle? 3, 5, 8
Back
No, because 3 + 5 is not greater than 8.
4.
FLASHCARD QUESTION
Front
Will these side lengths make a triangle? 5 cm, 7 cm, 9 cm
Back
Yes, because 5 + 7 > 9, 5 + 9 > 7, and 7 + 9 > 5.
5.
FLASHCARD QUESTION
Front
Identify the shortest side measure from QP, QM, MP if QM = 3 cm, QP = 4 cm, MP = 5 cm.
Back
QM is the shortest side measure.
6.
FLASHCARD QUESTION
Front
List the angles in order by measure, smallest to largest: ∠B, ∠A, ∠C
Back
∠A, ∠C, ∠B.
7.
FLASHCARD QUESTION
Front
If one side of a triangle is 10 cm and the other two sides are 6 cm and 8 cm, can it form a triangle?
Back
Yes, because 6 + 8 > 10, 6 + 10 > 8, and 8 + 10 > 6.
