The video tutorial explains how to determine if given angle or side measurements can form a triangle. It covers the Triangle Sum Theorem and its converse, demonstrating how to verify if three angles can form a triangle. The Triangle Inequality Theorem is also discussed, showing how to check if three side lengths can form a triangle using inequalities. Examples are provided to illustrate these concepts.

What is the sum of the interior angles of a triangle according to the Triangle Sum Theorem?

• 90 degrees

• 360 degrees

• 270 degrees

• 180 degrees

If three angles add up to 180 degrees, what can be concluded about these angles?

• They form a square

• They form a triangle

• They form a pentagon

• They form a hexagon

Which theorem helps determine if three side lengths can form a triangle?

• Converse Theorem

• Triangle Sum Theorem

• Triangle Inequality Theorem

• Pythagorean Theorem

According to the Triangle Inequality Theorem, what must be true for any two sides of a triangle?

• Their sum must be less than the third side

• Their sum must be twice the third side

• Their sum must be equal to the third side

• Their sum must be greater than the third side

If the sides of a triangle are 2, 14, and 18, can they form a triangle?

• Yes, because 2 + 18 is greater than 14

• No, because 14 + 18 is not greater than 2

• Yes, because all sides are positive

• No, because 2 + 14 is not greater than 18

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

• 5, 5, 10

• 3, 4, 8

• 6, 7, 12

• 1, 2, 3

What is the result of adding the sides 8, 9, and 3 to check if they form a triangle?

• They do not form a triangle

• They form a triangle because 9 + 3 > 8

• They form a triangle because 8 + 9 > 3

• They form a triangle because 8 + 3 > 9
