3.   Note:  Dotted lines represent lines behind the figure (i.e. 3-D representation).







Answer Key

1. C
The inside and larger shapes are reversed.
2. D
The shaded area is divided in half in the second figure.
3. D
The relation is the same figure rotated to the right.
4. B
The relation is the number of dots is one-half the number of sides.
5. C
The pattern is the same figure with a dot inside.
6. A
The relation is the same figure smaller, plus another figure with one more side.

  1. Shouldn’t the answer to #3 be C instead of D? C is the same shape rotated right, whereas D has dotted lines, making it different from the original.

    1. D is the correct answer. The dotted lins show the cut out view ‘behind’ the figure that you wouldn’t see. Without the dotted lines, (choice C) the figure is in relief.

    2. C is actually a rotation that is not 90 degrees. The face of the rectangle is along a diagonal which isn’t in line with D that is a direct 90 degree rotation clockwise.

  2. Please re-think number 3. How does tilting original figure to the right automatically reveal the dotted lines ?

  3. #3 the example shows an oval turned on its side. no magic lines connecting anything in the rear. if that’s the case than the answer on 3 should be C because you’re simply rotating the image. there are no lines to show what it looks like behind the surface. so D is not the correct answer.

  4. May be a bit late, but I would also recommend a re-think of how you present #3. I understand your reasoning for D being the correct answer, but you do not state in the question anywhere that ONLY dotted lines can represent the sides behind the figure. Should you have stated that then #3’s answer is obviously D; however, without that specification C is not necessarily wrong as without the specification of it being in relief being known to the test-taker, the taker can not possibly know that figure C is in relief.
    This confusion is a by-product of a 2D representation of 3D objects without clear specifications regarding their orientation. The question needs clarification in order for D to be the only correct answer.

    1. I totally agree with this. If they are saying the dotted lines are correct, the dotted lines should’ve been present in the example.

  5. Thank you for the discussion/suggestions, re. dotted lines and 2-D and 3-D representation. I have added a note to the questions to clarify.

    1. Comment does not clarify.

      Dotted lines must be present in the original else it will be interpreted as having no lines in depth and therefore when rotated, remain without lines in depth.
