- Congruence, Symmetry
Given the quadrilateral , the square , and the information that is the same distance from and , show that is symmetrical along segment .
- Recall the definition of line symmetry.
- Since and , is a line of symmetry for where .
- has the same area as because they share a base and have equal height. , so .
- We now know is a line of symmetry for and is a line of symmetry for , so and quadrilateral is symmetrical along .
