SIFT Simple Drawings and Figures 3

Question 1

A capital letter 'R' is reflected across a vertical axis. What does the result look like?

Accepted Answer

A mirror-image 'R' facing left

Answer

Reflecting 'R' across a vertical axis flips it horizontally, creating a backward (mirror-image) 'R'.

Question 2

A figure composed of two overlapping circles is rotated 360°. The result is:

Accepted Answer

Identical to the original

Answer

A full 360° rotation returns any figure to its exact original position and appearance.

Question 3

Which pair of figures demonstrates a rotation rather than a reflection?

Accepted Answer

A 'p' and a 'b'

Answer

'p' rotated 180° becomes 'b', making it a rotation; the others involve reflections across an axis.

Question 4

A triangle has vertices at (1,1), (4,1), and (1,4). After reflecting across the line y = x, where is the vertex originally at (4,1)?

Accepted Answer

(1,4)

Answer

Reflecting across y = x swaps the x and y coordinates, so (4,1) becomes (1,4).

Question 5

A clock face (with no numbers) is rotated 90° counter-clockwise. Where does the 12 o'clock position now point?

Accepted Answer

9 o'clock direction

Answer

Rotating the top (12) counter-clockwise 90° moves it to where 9 o'clock was, which is now pointing left.
