SIFT Simple Drawings and Figures 4

Question 1

A figure shows a star with one point aimed directly upward. After two successive 90° clockwise rotations, where does that point aim?

Accepted Answer

Down

Answer

Two 90° clockwise rotations total 180°, sending the top point directly downward.

Question 2

Which transformation changes the size of a figure?

Accepted Answer

Dilation

Answer

Dilation scales a figure by a factor, enlarging or reducing it, while the other three are rigid motions that preserve size.

Question 3

A right-pointing arrow is reflected across a horizontal axis. The result is:

Accepted Answer

A right-pointing arrow (unchanged)

Answer

Reflecting a horizontal arrow across a horizontal axis flips it top-to-bottom but leaves its left-right direction unchanged.

Question 4

A simple closed figure has 0 lines of symmetry and rotational symmetry of order 1 only. This describes a:

Accepted Answer

Scalene triangle

Answer

A scalene triangle has no equal sides, no lines of symmetry, and only trivial (360°) rotational symmetry.

Question 5

When comparing a target figure to answer choices on the SIFT, one choice appears to be the target flipped, not rotated. You should:

Accepted Answer

Eliminate it, because it is a reflection and not a rotation

Answer

On the SIFT Simple Drawings subtest, reflections (mirror images) are distractors—only the correctly rotated figure is the right answer.
