Explanation:

• Reflection: In math, reflection means flipping a figure over a line. So "Flipped over" (Option B) is correct.
• Coefficient: It is the number multiplied by a variable. So "The number in front of a variable" (Option C) is correct.
• Binomial: A polynomial with two terms. So "A polynomial with 2 terms" (Option A) is correct.
• Vertex: A corner of a shape. So "A corner of a shape" (Option A) is correct.
• Acute: An angle less than 90 degrees. So "Angles are less than 90 degrees. Triangle all angles are less than" (Option B) is correct (assuming it means angles less than 90 degrees).
• Sum: The result of addition. So "The result when you add numbers" (Option B) is correct.

Answer:

1. B. Flipped over
2. C. The number in front of a variable
3. A. A polynomial with 2 terms
4. A. A corner of a shape
5. B. Angles are less than 90 degrees. Triangle all angles are less than
6. B. The result when you add numbers
