14 B look at the bottom legs. The one in the middle. It is too sharp. E they are both the same angle. Pushed in from the left side.
 
for 14, you immediately cancel out choices A and D (D can't be true cause for it to be true, you got to have the bottom base in an angle like it shows in choice B)

now we go into more detail for the remaining answer choices B, C, E. Choice C got more steeper lines. The triangles of the main object are more broader. C's out.

Choice B looks pretty nice, but if you extend the angle of the half cut base in our main object, it meets a little above the middle of the triangle leg. the angle points near the peak of the triangle. and in choice B the half base angle points at near the base of the triangle. I don't know how to explain this honestly, and I don't know if my explanation is correct, but this is how I figured it could not be B.

From the left side view, Choice E fits perfectly.

Hope this helped?
 
yea i see what u mean now thanks. it was a hard angle to see at (well for me at least)

yeah the correct ans was dddec. thanks to all of them. i had the question for 14th and 12th one but now its clear. thank you all my frnds.

i will try to update more if i can so that we can do a group discussion...!!!
 
So i am really bad at this, and i cant ever figure out the right answers..

like for number 11 can you explain why it isn't A and it is D.. doesnt D look to big from the top to be coming in?

can someone explain to me how they are looking at these to get them correct most of the time..

its not A because if u look at the legs of the letter formed (in the diagram it forms the letter A), the leg closer to u is longer than the leg farther from u (for the answer choice). but in actuality they are more close to the same length (the legs i mean).
