Answer:
5. corresponding sides -> Sides paired with one another in a one-to-one correspondence between figures.
4. congruent figures -> If a one-to-one correspondence between the parts of two figures is such that the corresponding parts are equal, then the figures are congruent.
2. included side -> The side of a triangle that is formed by the common side of two angles.
1. one-to-one correspondence -> A situation for which each member of a set, such as angles of a triangle, can be paired with one and only one member of another set.
6. included angle -> The angle formed by two sides of a triangle
3. corresponding angles -> Angles paired with one another in a one-to-one correspondence between geometric figures.
