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.

FLASHCARD QUESTION
Front
If the lengths of two sides of a triangle are 10 and 15, what is the range of possible lengths for the third side?
Back
The range of possible lengths for the third side is 5 < x < 25.

FLASHCARD QUESTION
Front
Which of the following sets of lengths can represent the sides of a triangle: 32, 34, 60 or 28, 30, 58?
Back
The lengths 28, 30, 58 cannot represent the sides of a triangle.

In triangle ABC, if AB = 5, AC = 7, and BC = 12, does it satisfy the Triangle Inequality Theorem?
Back
No, because 5 + 7 is not greater than 12.

FLASHCARD QUESTION
Front
What does it mean for two triangles to be congruent?
Back
Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.
