7 h if any of the following nets will give a triangular pyra

7. h, if any, of the following nets will give a triangular pyramid? hic AVV a. b. b. C. d.

Solution

Net C will give a triangular pyramid.

If we assume the middle triangle as base then left triangle will give left side of base when folded and right side of triangle will give right side of base when folded, similarly upper triangle will give back side of pyramid, which will complete the triangular pyramid,

In part A

if we assume first triangle as base then the next triangle will give right side of pyramid, but we will not get rest of the sides of pyramid without breaking the net.

if we assume second triangle as base then the next triangle in right will give right side of pyramid and next triangle in left will give left side of pyramid, but we will not get backside of pyramid without breaking the net.

In part B.

if we assume (upper left triangle) as base then the next triangle will give right side of pyramid, but we will not get rest of the sides of pyramid without breaking the net.

if we assume (upper right triangle) as base then the next triangle in downside will give front side of pyramid and next triangle in left will give left side of pyramid, but we will not get right side of pyramid without breaking the net.

In part D.

Try to Visualize on your own and let me know if you are able to find out why it will not make a triangular pyramid. If you have any problem comment below I will explain it.
