Triangle area is one-half times base times height: 1/2 × 8 × 5 = 20.

3. QuestionMultiple choice

Which pair of angles are complementary?

Please select an answer first.

Correct answer: C

The correct answer is 35 degrees and 55 degrees.

  1. Read the math task: Identify the quantities, operation, fraction, decimal, measurement, data relationship, or shape in the question.
  2. Show the reasoning: Complementary angles add to 90 degrees, and 35 + 55 = 90.
  3. Check the answer: Choose the option that matches the calculation, model, or mathematical definition.

Complementary angles add to 90 degrees, and 35 + 55 = 90.

4. QuestionMultiple choice

Please select an answer first.

Correct answer: D

The correct answer is 6 units.

  1. Read the math task: Identify the quantities, operation, fraction, decimal, measurement, data relationship, or shape in the question.
  2. Show the reasoning: Two lengths use 18 units; the remaining 12 units make two widths of 6.
  3. Check the answer: Choose the option that matches the calculation, model, or mathematical definition.

Two lengths use 18 units; the remaining 12 units make two widths of 6.

5. QuestionMultiple choice

Which shape has exactly one line of symmetry?

Please select an answer first.

Correct answer: A

The correct answer is Isosceles triangle.

  1. Read the math task: Identify the quantities, operation, fraction, decimal, measurement, data relationship, or shape in the question.
  2. Show the reasoning: A non-equilateral isosceles triangle has one line of symmetry.
  3. Check the answer: Choose the option that matches the calculation, model, or mathematical definition.

A non-equilateral isosceles triangle has one line of symmetry.

6. QuestionMultiple choice

A coordinate grid point is at (4, 2). What does the 4 represent?

Please select an answer first.

Correct answer: B

The correct answer is The horizontal position.

  1. Read the math task: Identify the quantities, operation, fraction, decimal, measurement, data relationship, or shape in the question.
  2. Show the reasoning: The first coordinate gives the horizontal position.
  3. Check the answer: Choose the option that matches the calculation, model, or mathematical definition.

The first coordinate gives the horizontal position.

7. QuestionMultiple choice

Which point is in the same column as (3, 5)?

Please select an answer first.

Correct answer: C

The correct answer is (3, 1).

  1. Read the math task: Identify the quantities, operation, fraction, decimal, measurement, data relationship, or shape in the question.
  2. Show the reasoning: Points in the same column have the same first coordinate, 3.
  3. Check the answer: Choose the option that matches the calculation, model, or mathematical definition.

Points in the same column have the same first coordinate, 3.

8. QuestionMultiple choice

A shape is divided into 12 equal parts, and 9 are shaded. What fraction is shaded?

Please select an answer first.

Correct answer: D

The correct answer is 3/4.

  1. Read the math task: Identify the quantities, operation, fraction, decimal, measurement, data relationship, or shape in the question.

9. QuestionMultiple choice

A student claims that 3/5 is greater than 2/3 because 3 is greater than 2. Why is the claim incorrect?

Please select an answer first.

Correct answer: A

The correct answer is The denominators are different, so the fractions must be compared using equivalent values..

  1. Read the math task: Identify the quantities, operation, fraction, decimal, measurement, data relationship, or shape in the question.
  2. Show the reasoning: Different denominators mean the numerators alone do not determine which fraction is greater.
  3. Check the answer: Choose the option that matches the calculation, model, or mathematical definition.

Different denominators mean the numerators alone do not determine which fraction is greater.

10. QuestionMultiple choice

Which equation can check 2.6 + 1.75 = 4.35?

Please select an answer first.

Correct answer: B

The correct answer is 4.35 − 1.75 = 2.6.
