Three line segments have measures of 13 units, 7 units, and 5 units. Will the segments form a triangle?

• Yes, because the sum of the lengths of any two sides is greater than the length of the third side.

• No, because the sum of the lengths of any two sides is less than the length of the third side.

• Yes, because the sum of the lengths of any two sides is equal to the length of the third side.

• No, because the sum of the lengths of any two sides is equal to the length of the third side.

Determine if ΔABC with ∠A = 40°, ∠B = 65°, and ∠C = 75° will form a unique triangle or more than one triangle.

• It will form a unique triangle because the sum of the angles is 180°.

• It will not form a triangle because the sum of the angles is not 180°.

• It will form more than one triangle because the angles are not all the same.

• It will not form a triangle because one angle is greater than 90°.
