1. QuestionMultiple choice

A 6-foot person casts a 4-foot shadow. At the same time, a tree casts a 14-foot shadow. What is the height of the tree?

Please select an answer first.

Correct answer: A

The correct answer is 21 feet.

  1. Identify the geometry idea: Decide whether the question uses angles, triangles, similarity, transformations, coordinates, circles, measurement, or proof.
  2. Show the reasoning: Set up the proportion 6/4 = h/14. Solving gives h = 21 feet.
  3. Check the result: Review the diagram relationships, units, signs, and geometric definitions before choosing the answer.

Set up the proportion 6/4 = h/14. Solving gives h = 21 feet.

  2. Show the reasoning: Opposite sides of a parallelogram are both parallel and congruent.
  3. Check the result: Review the diagram relationships, units, signs, and geometric definitions before choosing the answer.

Opposite sides of a parallelogram are both parallel and congruent.

3. QuestionMultiple choice

Which statement is always true for a rhombus?

Please select an answer first.

Correct answer: C

The correct answer is All four sides are congruent.

  1. Identify the geometry idea: Decide whether the question uses angles, triangles, similarity, transformations, coordinates, circles, measurement, or proof.
  2. Show the reasoning: A rhombus is a parallelogram with four congruent sides.
  3. Check the result: Review the diagram relationships, units, signs, and geometric definitions before choosing the answer.

A rhombus is a parallelogram with four congruent sides.

4. QuestionMultiple choice

A rectangle has length x + 3 and width x. Its area is 40. Which equation models the situation?

Please select an answer first.

Correct answer: D

The correct answer is x(x+3)=40x(x + 3) = 40.

  1. Identify the geometry idea: Decide whether the question uses angles, triangles, similarity, transformations, coordinates, circles, measurement, or proof.
  2. Show the reasoning: Area equals length times width, so x(x + 3) = 40.
  3. Check the result: Review the diagram relationships, units, signs, and geometric definitions before choosing the answer.

Area equals length times width, so x(x + 3) = 40.

5. QuestionMultiple choice

What is the scale factor from a figure with area 12 square units to a similar figure with area 108 square units?

Please select an answer first.

Correct answer: A

The correct answer is 33.

  1. Identify the geometry idea: Decide whether the question uses angles, triangles, similarity, transformations, coordinates, circles, measurement, or proof.
  2. Show the reasoning: Area scale factor is the square of the length scale factor: 108/12 = 9, so the length scale factor is 3.
  3. Check the result: Review the diagram relationships, units, signs, and geometric definitions before choosing the answer.

Area scale factor is the square of the length scale factor: 108/12 = 9, so the length scale factor is 3.

6. QuestionMultiple choice

A transformation maps every point (x,y)(x,y) to (x+5,y−2)(x + 5, y − 2). Which transformation is this?

Please select an answer first.

Correct answer: B

The correct answer is A translation 5 units right and 2 units down.

  1. Identify the geometry idea: Decide whether the question uses angles, triangles, similarity, transformations, coordinates, circles, measurement, or proof.
  2. Show the reasoning: Adding 5 to x moves right and subtracting 2 from y moves down.
  3. Check the result: Review the diagram relationships, units, signs, and geometric definitions before choosing the answer.

Adding 5 to x moves right and subtracting 2 from y moves down.

7. QuestionMultiple choice

Which condition proves a quadrilateral is a parallelogram?

Please select an answer first.

Correct answer: C

The correct answer is Both pairs of opposite sides are congruent.

  1. Identify the geometry idea: Decide whether the question uses angles, triangles, similarity, transformations, coordinates, circles, measurement, or proof.
