Logical reasoning questions

1)




2)



I think this one is D)
Any help would be highly appreciated!

1) Consider the four triangles. Using T, B, L, R (top, bottom, left, right) to label the triangles:

In the 2nd diagram only TR and BR have changed.
3rd diagram : only BR and BL have changed
4th diagram : only BL and TL have changed
5th diagram : only TL and TR have changed

Does that help?

I'm not confident with 2) but I'd also go for D by the fact that for each diagram, the inner shape is the outer shape if you go back two diagrams. But I cant see why the next outer shape will be a square. So either the outer shape is random or I'm missing something - the latter is more likely.

Genius!

Thank you very much Sir
