Check all that apply

2. ABCD is a rectangle. Trapezoid AEFB is congruent to trapezoid CFED. G is the midpoint of segment EF.             Select all the ways we could describe the rigid transformation that takes AEFB  to CFED.

Check all that apply

3. Regular hexagon ABCDEF is inscribed in a circle with center H. a.       What is the image of segment BC after a reflection over line FC ?

3. Regular hexagon ABCDEF is inscribed in a circle with center H. b. What is the image of segment BC after a 120-degree clockwise rotation about point H?

4. Describe a sequence of transformations that take isosceles trapezoid T to its image T'.
