Q1.Which statement below is correct?

Reflections and Translations always look the sameYou can easily tell if congruent shapes have been reflected or translatedIt is easier to tell if a shape has been translated or reflected if the vertices are marked in a colour or labelledReflections and Translations never look the same

Q3.If we are reflecting a shape onto the x axis then which of the following is correct?

Both the x and y coordinates of the reflected shapes must stay the sameBoth the x and y coordinates of the reflected shapes must changeThe x coordinate will definitely stay the sameThe y coordinate will definitely stay the same
