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.
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.
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.
Nope. The base of c is a different shape, and it is not a square-based pyramid.
3 sides vs 4
Sorry both have 4 sides but its the actual angle they are facing
Sorry both have 4 sides but its the actual angle they are facing and thats why its d
Please re-think number 3. How does tilting original figure to the right automatically reveal the dotted lines ?
The dotted links show the shape of the figure ‘behind’ the figure, as in ‘see-through.’
Thank you very much for sharing. This is a great!!
#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.
See comments below – no ‘magic’ lines – the dotted lines show the ‘see through’ view
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.
I totally agree with this. If they are saying the dotted lines are correct, the dotted lines should’ve been present in the example.
I agree as well. I think Taylor is correct.
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.
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.
Me got D too. The dotted lins show the cut out view
Dotted lines are a giving what they mean. If one looks closly at the leading edge of the tryangle one will see why its d
