Suppose That You Are Taking a Course in Geometry

question 27

Multiple Choice

Suppose that you are taking a course in geometry. You are trying to determine whether two geometric shapes are identical, so you mentally rotate one of the figures in a clockwise fashion. You are likely to find that

• A) you will not be very accurate in this task, because mental imagery is very poor for geometric figures.
• B) you will take more time than if you had to rotate the figure in a 3-dimensional plane (e.g., away from you).
• C) you will rotate the figure more quickly than if you had to rotate it in a counterclockwise fashion.
• D) you will take longer to rotate it 120° than 40°.
