Answer 2

if you divide a right triangle that way you form two "smaller" right triangles
It turns out those two triangles are similar to each other and similar to the original big triangle.

Answer 3

A?

Answer 4

nope not A

Answer 5

in choice A the "sign" means congruent (exactly the same size and shape)
none of the triangles are the same size, but they are the same shape (and different sizes)
