Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected over the x-axis. The reflected figure is labeled figure C. Which best explains why figure A is congruent to figure C?

On a coordinate plane, triangle A has points (1, negative 2), (3, negative 2), (3, negative 5). Triangle B has points (4, 0), (6, 0), (6, negative 3). Triangle C has points (4, 0), (6, 0), (6, 3).

Answer choices:

1. A Is congruent to B and B Is congruent to C
2. A Is congruent to A, B Is congruent to B, C Is congruent to C
3. Each triangle is a right triangle.
4. Each triangle is an isosceles triangle.
