Question

02.03)Figure EFGH is reflected about the y-axis to obtain figure E’F’G’H’:

A coordinate plane is shown. Figure EFGH has vertices E at negative 5 comma 4, F at negative 5 comma 1, G at negative 3 comma 2, and H at negative 1 comma 6. Figure E prime F prime G prime H prime has vertices at E prime 5 comma 4, F prime 5 comma 1, G prime 3 comma 2 and H prime 1 comma 6.

Which statement best describes the relationship between the two figures?
Figure EFGH is congruent to figure E’F’G’H’. Figure EFGH is bigger than figure E’F’G’H’. The measure of angle H is equal to the measure of angle E’

Answer 2

Hint:
reflections preserve measures of sides and angles between sides, and area. The preimage is therefore congruent to the image. However, the orientations of the sides are not preserved.
