Which of the below mean the same as a line of reflection?

The distance between the mirror line and A is 12 squares

The distance between the mirror line and A is 24 squares

The distance between the mirror line and A' is 6 squares

The distance between the mirror line and A' is also 12 squares

If the distance between point A and its reflected point (A') is 12 squares then which of the statements below is true?

The distance between B and B' is 18 squares

The distance between B and B' is 4.5 squares

The distance between B and B' is also 9 squares

The distance between the mirror line and B' is 4.5 squares

If distance between point B and a mirror line is 9 squares, then which of the following statements below is true?

The coordinates (-4,-4) and (-4,-2) are reflected, after reflection (-4,-4) becomes (3,3) and (-4,-2) becomes (1,3), which of the following statements is true?

A point with coordinates (1,-4) and (1,-3) are reflected to become (-3,-4) and (-3,-3) what do we know about the mirror line?

The x axis cannot be a line of reflection

When shapes are reflected some of the coordinates can change

Which of the following statements is NOT correct?

Both the x and y coordinates of the reflected shapes must change

Both the x and y coordinates of the reflected shapes must stay the same

The x coordinate will definitely stay the same

The y coordinate will definitely stay the same

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

If we are reflecting a shape onto the y axis then which of the following statements is correct?

A triangle with the coordinates (-5,6), (-5,7) and (-4,7) is reflected by a line of reflection along the y axis, which of the below are the correct reflected coordinates?

A point with coordinates (-4,0) is reflected by a line of reflection along the x axis, what would its new reflected coordinates be?
