Understanding Triangle Side Lengths

How many sides are required to form a triangle?

• Five

• Four

• Two

• Three

According to the triangle inequality theorem, what must be true about the sum of any two sides of a triangle?

• It must be less than the third side.

• It must be equal to the third side.

• It must be greater than the third side.

• It can be any value.

If a triangle has sides of lengths 3, 4, and 6, does it satisfy the triangle inequality theorem?

• Yes, it satisfies the theorem.

• It cannot be determined.

• No, it does not satisfy the theorem.

• It depends on the angles.

Which of the following sets of side lengths can form a triangle?

• 5, 5, 10

• 1, 1, 3

• 3, 4, 5

• 2, 2, 5

What happens if the sum of two sides of a triangle is equal to the third side?

• It forms a valid triangle.

• It forms an obtuse triangle.

• It forms a straight line, not a triangle.

• It forms a right triangle.
