thank you som much

First one :

Look at triangles A, D and E

Each is a right triangle with leg legths of 2 and 3

This insures that their hypotenuses are also the same......so....by they are congruent by Leg-Leg congruency

which ones look the same

A, D and E are all the same.....they are just rotations of the same congruent right triangle...

D is for 2) since it's just rotated.

i got it wrong dont know how i just tried it plz explain plz

thank you

Huh???...I agree with Hugo.....if you rotate "X" 90° counterclockwise, you get "D"

Last one :

a) A and C are congruent to E

b) If A and C are congruent to E, they are also congruent to each other
