Answer:
• Each pair of triangles is congruent
~You can tell that each pair is congruent for the following reasons: (1) The legs, or sides, of the triangles in both #1 & #3 are both the same number. (2) The tick marks in #2 are the same, meaning the side lengths are similar.
• Both triangles in each pair are right triangles.
• The triangle pairs in #1 & #3 are rotations, while the triangle pair for #2 is a translation.
I was unaware of any specific answers, so I hope this is helpful!!!
