Question

Given an isosceles trapezoid, which reflection carries the figure onto itself?

1. 
   
2. A.
3. Reflect the figure across a line through the midpoints of the sides.
4. 
   
5. B.
6. Reflect the figure across a line through opposite vertices.
7. 
   
8. C.
9. Reflect the figure across a line through the midpoints of the bases.
10. 
    
11. D.
12. There is no reflection that carries the figure onto itself.

Answer 1

C if you put a midpoint on both the top and the bottom bases and draw a vertical line across it and reflect the figure across that line, that would carry the figure onto itself.

Imagine if you were to put a mirror vertically on the center of that isosceles trapezoid, you would see the other half of the trapezoid in the mirror, thus creating a whole trapezoid.
