A Relective caution sign is designed in the shape of a kite so that it is clearly visible at night. It maintains symmetry. To ensure proper alignment, a metal strip is fixed along one diagonal of the kite.
 
Based on the given information solve the following questions
 
1. While inspecting the reflector, the engineer notices a key feature that confirms it is a kite.
 
 
2. Which property of a kite explains why only one diagonal is chosen for support in the reflector?
 
3. The Relective caution sign splits into two congruent triangular regions. What does this reveal about that diagonal?
 
4. The reflector does not have all equal angles. Which statement best explains the angle equality seen during inspection?
