Exploring reflections and translations using coordinates

Maths

Transformations

The reflected shape has the same x coordinate as the original shape

The reflected shape has the same y coordinate as the original shape

Which of the following happens when a shape is reflected by a line of reflection along the x-axis?

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  a shape is reflected by a line of reflection along the x axis then which of the following is correct?

The triangle has been reflected onto the x-axis

The triangle has been reflected onto the y-axis

If a triangle has the coordinates (1,3), (1,4), (2,3) and after a transformation becomes (1,-3), (1,-4) and (2,-3), which if the below have happened?

If a triangle which has the coordinates (1,-1), (1,-3) and (3,-3) is reflected by a line of reflection along the y-axis, what will it's new reflected coordinates be?

A triangle with coordinates (-2,-2), (-2,-4) and (-4,-4) is reflected first by a line of reflection along the x-axis, and then reflected by a line of reflection along the y-axis, what will the new coordinates be?

Reflection is the only type of translation

Reflections and translations are types of transformations

Transformations and reflections are types of translations

Transformations are a type of translation

Which of the statements below is correct?

When we reflect a square across the y axis we can also translate it left/right to the same position

When we reflect a square across the y-axis we can also translate it up/down

When we reflect a square across the y-axis we cannot also translate the original shape so it is the same as the translated square

None of the above, it depends on the actual shape

The shape would be translated 1 square away from the original

The shape would be translated to the left

The shape would go back to it's original position

What would happen if we reflected a shape onto the x-axis and then onto the y-axis and then back onto the x-axis and then onto the y-axis?

When we reflect a square onto the x-axis the size of the shape changes

When we reflect a square onto the x-axis we can also translate it left/right

When we reflect a square onto the x-axis we can also translate it up/down

When we reflect a square onto the x-axis, the reflected shape must pass through the origin

If we reflect a rectangle across the x-axis then we can also say that this shape has been translated either up or down

If we reflect a rectangle across the y-axis we can also say that this shape has been translated either to the left or to the right

If we reflect a right-angled triangle across the y-axis we can also say that this shape has been translated either to the left or right

None of the above. It would depend on the orientation of the right angled triangle

Which of the statements below is NOT correct?
