Hey hey!
To figure out the congruence you have to look at the lines and ticks on both triangles.
So when it gives you one letter you know it's asking for an angle.
And when it gives you two letters you know it's a segment.
When it gives you three letters you're looking for an angle.
A)
<A = <X
<B = <Z
<C = <Y
B)
AB = XZ
AC = XY
BC = ZY
C)
This one is a little tricky, so when it gives you a three-letter angle you have to look at the 'samwitched' letter, which in this case would be A.
To answer this first you have to figure out what angle corresponds to A which would be X.
And then to answer you could say either <u>YXZ or ZXY</u> as long as the X is in the middle it's okay.
I hope this helps a bit :)
